Question

Периметр прямоугольника равен 34 см. а одна из его сторон равна 5 см. найдите диагональ прямоугольника

Answer 1

34-(5Х2)=24 - две оставшиеся стороны
24:2=12 - одна осторона
12Х12+5Х5=144+25=169
квадратный корень из 169=13
Ответ:диагональ=13см

Answer 2

Это и ленивый знает.
1. Периметр - сторона * 2
2. Остаток разделить на 2 
3 Теорема пифагора ( диагональ - это гипотенуза)

Answer 3

Finding the Diagonal of a Rectangle

To find the diagonal of a rectangle, we can use the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

In the case of a rectangle, the diagonal is the hypotenuse of a right triangle formed by the two sides of the rectangle. Let's denote the length of one side of the rectangle as a and the length of the other side as b.

Using the Pythagorean theorem, we can express the relationship between the sides of the rectangle and the diagonal as follows:

diagonal^2 = a^2 + b^2

In this case, we are given that the perimeter of the rectangle is 34 cm and one of its sides is 5 cm. To
