- Perimeter of rhombus
The area of the rhombus is 32 cm². One side measures 10 cm. The height on the other side measures 5 cm. What is the perimeter of this rhombus? - The quadrilateral
The quadrilateral ABCD is composed of two right triangles, ABD and BCD. For side lengths: |AD| = 3 cm, | BC | = 12 cm, | BD | = 5 cm. How many square centimeters (area) does the quadrilateral ABCD have? The angles of DAB and DBC are right. - Sprinkler irrigation area
The rotary sprinkler has a spray of 18 m. How much land can it irrigate from one place? - Circle diameter
The length of the circle is 87.92 cm. Calculate the size of the circle diameter. Express the result in centimeters. - Calculation - isosceles
Calculate the area and perimeter of an isosceles triangle if given: base a: 6 cm, height to the base: 4 cm. - Parallelogram - A+p
Calculate the area and perimeter of a parallelogram if side a = 5.2 cm and height to side is va = 4 cm (it is a parallelogram, not a triangle) - Perimeter of a rectangle
Find the perimeter of a rectangle with a length of 1/2 feet and a width of 1 1/3 feet. - Height of right RT
The right triangle ABC has a hypotenuse c 9 cm long and a part of the hypotenuse cb = 3 cm. How long is the height of this right triangle? - Trapezoid perimeter area
In the trapezoid, it is given: all four sides a = 51 cm; b = 30 cm; c = 18 cm; d = 27 cm; and height v = 24 cm; Calculate: perimeter o=? and area S=? - Isosceles trapezoid
Calculate the length of the arms and the area of the isosceles trapezoid if you know the following parameters: o = 20 cm a = 10 cm, c = 4 cm h = 2 cm - The goldfish
The goldfish floats close to the wall of a circular pool with a radius of 10 m. How many meters does it pass when it makes two circuits in the pool? (indicate the result to one decimal place) - Right trapezoid
Calculate the area of a rectangular trapezoid whose perpendicular arm is 27 mm long and the bases are 33 mm and 19 mm long. - Woman's day
We can easily make a heart for mothers for Woman's day by drawing two semicircles on the two upper sides of the square standing on their top. What is the radius of the circle circumscribed by this heart when the length of the side of the square is 1? - Ladder wall length
A ladder leans against the wall. It touches the wall at the height of 340 cm, and its lower end is 160 cm away from the wall. How long is the ladder? Express the result to the nearest centimeter. - Rectangle's dimensions
The rectangle has an area of 147 cm². One of its sides is three times longer than the other side. We increase the shorter side of the rectangle by 8 cm. By how many cm² will the new rectangle's area be larger than the original rectangle? - Peter's rectangle Peter had a rectangle 2 cm wide and of unknown length. The line had a 2 cm rectangle whose length was equal to the perimeter of Peter's rectangle. When they put the rectangles together with their widths, they got a new rectangle with a circumference of 63
- Trapezoid perimeter base
An isosceles trapezoid has one base twice as short as the other. Its area is 42 cm², and its height is 4 cm. Calculate its circumference if you know that the arm is 5.3 cm long. - Fountain sidewalk area
A 2 m wide sidewalk is built around the circular fountain. The radii of the circles that delimit the path on both sides are 4:3. What area in square meters does this sidewalk occupy? - Trapezoid complete
Calculate side b and the height of the trapezoid if a = 5.1 cm; c = 6.8 cm; d = 4.7 cm; circumference is 21 cm, and the area is 17.85 cm². - Darnell
Darnell is mountain climbing with Kirk and has just climbed a 9-meter vertical rock face. Kirk is standing at the bottom of the cliff, looking up at Darnell. If Kirk is 15 meters away from Darnell, how far away from the cliff is Kirk standing?
