Question

Длина диагонали прямоугольник 17см, а длина одной стороны 15 см. Найдите периметр

Answer 1

В прямоугольном тр.квадрат гипотенузы= квадоату катетлв, слежовательнл, длинадр. Сторлны=289-225=64 , корень= 8. Периметр=15+8)×2=46

Answer 2

Легко  найти  недостающую  сторону  прямоугольника  по  теореме  Пифагора =√(17-15)(17+15)=√2*2*16=2*4=8 (см) Кстати,  15  8   17 -  Пифагорова  тройка (одна  из). Можно запомнить
Теперь  периметр=(15+8)*2=46 см

Answer 3

Calculating the Perimeter of a Rectangle

To find the perimeter of a rectangle, we can use the formula: Perimeter (P) = 2 * (length + width)

Given: - Length of the diagonal = 17 cm - Length of one side = 15 cm

Using the given information, we can calculate the perimeter of the rectangle.

Calculation

We can use the Pythagorean theorem to find the length of the other side of the rectangle using the length of the diagonal and the length of one side.

The Pythagorean theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

Using the Pythagorean theorem: - Let's assume the length of the other side is 'x'. - We have: 17^2 = 15^2 + x^2

Solving for 'x': - 289 = 225 + x^2 - x^2 = 289 - 225 - x^2 = 64 - x = √64 - x = 8

Now that we have the length of both sides, we can calculate the perimeter using the formula: P = 2 * (15 + 8) P = 2 * 23 P = 46

Answer

The perimeter of the rectangle is 46 cm.
