- Point plane distance
Calculate the distance of point A[ 4; 2; -3 ] from the plane : 2x - 2y + z + 5 = 0 - Internal angles
The ABCD is an isosceles trapezoid, which holds: |AB| = 2 |BC| = 2 |CD| = 2 |DA|: On the BC side is a K point such that |BK| = 2 |KC|, on its side CD is the point L such that |CL| = 2 |LD|, and on its side DA, the point M is such that | DM | = 2 |MA|. Det - Hexagon floor parquet
The floor in the game tower has the shape of a regular hexagon with a side length of 5 m. How many pieces of parquet must be ordered to cover it if 25 pieces are needed for 1 square meter, and we must add a reserve of 10%? - We are solving K
At the beginning we have a square 12x12 cells. Divide this square into an arbitrary number of rectangles, where only one rule must hold, namely that there must not be two rectangles with identical dimensions. Next, for this division we calculate the numbe - Jewel
In a competition for the most beautiful jewel, a jewel with the following description won: on a silver plate in the shape of a square, four identical ruby rhombuses are mounted. The rhombuses touch with their vertices at the midpoints of the sides of the - Diameter of cent coins

Resize the square to 10:3. The original size is 3 cm. - Rectangle dimension change
Change both dimensions of the rectangle in a ratio of 5:3. Initially, the dimensions are 9 cm and 15 cm. What are the dimensions of the rectangle after the change? - Proportion of the continents
The area of Asia and Africa is 8:7, and the area of Europe and Africa is 5:6. In what proportion are the sizes of regions of Asia, Africa, and Europe? - Cutting square
We cut the circle with the highest possible diameter from a square with a side of 30 cm. How many percent of the square area is this circle? - Rhombus 29
One of the diagonals of a rhombus is equal to a side of the rhombus. Find the angles of the rhombus. - Stone squares
Draw two squares made of stones. They use a total of 34 stones. What are the side lengths of the squares? - Type of triangle
How do you determine the type of triangle if the angle ratio is 2:3:7? - Height ratio
In a general triangle, the aspect ratio a: b = 2:3. What is the ratio of heights va: vb? - Playground area
The fencing of the square playground cost € 462, while the 1 m fencing cost € 11. What is its playground area? - Rectangle - sides 4
The perimeter of the rectangle is 72 cm. Calculate the length of the sides that are in the ratio of 3:5. - Ratio of perimeters
Rectangle ABCD has dimensions 11 cm and 7 cm, and KLMN rectangle has dimensions 10 cm and 10 cm. Calculate the ratio of the perimeter ABCD and perimeter KLMN. - Circumference - a simple
What is the ratio of the circumference of any circle to its diameter? Write the result as a real number rounded to 2 decimal places. - Rectangle dimension increase
The area of the rectangle is 81.25 cm². If we increase its length by 5 mm, its area increases by 4%. Determine its dimensions. - A rectangle 12
