- Round skirt
The cut on the round skirt has the shape of an annulus. Determine how much m² of fabric will be consumed on an 80 cm long skirt. The waist circumference is a circle with a smaller radius of 69 cm. - Flakes
A circle was inscribed in the square. We draw a semicircle above each side of the square as above the diameter. This resulted in four chips. Which is bigger: the area of the middle square or the area of the four chips? - Octagon from rectangle
We cut the corners of a rectangular tablecloth with dimensions of 4 dm and 8 dm into isosceles triangles. Thus, the octagon formed had an area of 26 dm². How many dm² of tablecloth do we cut down? - Internal and external angles
Calculate a triangle's remaining internal and external angles if you know the internal angle γ (gamma) = 34 degrees and one exterior angle is 78 degrees and 40 '. Determine what kind of triangle it is from the size of its angles. - Right trapezoid
The right trapezoid has bases 3.2 cm and 62 mm long. The shorter leg has a length of 0.25 dm. Calculate the lengths of the diagonals and the second leg. - Garden
The rectangular garden is 72 m long and 25 m wide. Calculate by how much m² its area will be reduced if it is surrounded by an ornamental fence 50 cm wide. - Sea
How far can you see from the ship's mast, whose peak is at 9 meters above sea level? (Earth's radius is 6370 km). - Exist triangle
Which of the following set of numbers could not represent the three sides of a triangle A. 13,22,34 B. 8,20,30 C. 10,14,23 D. 15,25,37 - Boards needed
The area is 5m x 59dm. How many boards will it need if one board has 30cm x 37 cm dimensions? - Triangle land fencing
The land has the shape of an obtuse triangle with sides of 40m, 30, and 60m. Determine the minimum mesh length for fencing and the land area in ares. - Tree ladder height
How tall is the tree if I lean a 2-meter-long ladder against it? The ladder is 0.7 m away from the tree, and the top of the ladder rests against the tree at 2/3 of its height. - Grass seed
Pearl wants to buy grass seed to cover her whole lawn with dimensions 7 x 11 meters, except for the pool. The pool is 5 3/4m by 3 1/2 m. Find the area the grass seed needs to cover. - The cellar
Mr. Novák has a cellar, and the cellar window in the chalet is a 0.6-meter square window. The window wishes to place an X-shaped grid in a square. He uses iron welded bars. Calculate the lengths of individual bars and the total length of the bars he has t - Tailor
Tailor has an estimated 11 meters of 80 cm wide fabric. He will shape wholly seven rectangles measuring 80 x 150 cm, and no fabric will remain. How much fabric does he have? - Road embankment
Road embankment has a cross-section shape of an isosceles trapezoid with bases 7 m and 10 m and 5 m long leg. How many cubic meters of soil is in an embankment length of 1198 meters? - Steps
How many steps do you save if you go square estate for diagonal (crosswise) rather than circumvent the two sides of its perimeter with 458 steps? - Triangle area grid
Each square of the net has an area of 25 mm². Calculate the area of the DEF triangle in cm². Express the result as a decimal number to three decimal places. - Area and perimeter 2
Find the area and the perimeter of a rectangle of length 45 1/2 cm and breadth 16 2/3 cm. - Tractor wheel turns
Five-year-old Patrik got a tractor. The smaller wheel of the tractor has a circumference of 18 cm, and the giant wheel of the tractor has a circumference of 7 cm larger. Calculate how many times the larger tractor wheel turns on a 10 m track. - Isosceles triangle area
