Question

Используя формулу для нахождения перимитра квадрата выразите длину стороны квадрата а через перимитер р найдите а если р равен 8 дм

Answer 1

Длинна стороны квадрата равна периметру деленному на 4.
a = p/4

Если р=8 дм
то a=8/4=2 дм = 20 см

Answer 2

Formula for Finding the Perimeter of a Square

To find the perimeter of a square, you can use the formula:

P = 4a, where P is the perimeter and a is the length of one side of the square.

Expressing the Length of the Side of a Square (a) in terms of the Perimeter (P)

To express the length of the side of a square (a) in terms of the perimeter (P), you can rearrange the formula as follows:

a = P / 4

Finding the Length of the Side of the Square (a) when the Perimeter (P) is 8 dm

Given that the perimeter (P) is 8 dm, we can use the formula to find the length of the side of the square (a):

a = 8 / 4 a = 2 dm

So, when the perimeter (P) is 8 dm, the length of the side of the square (a) is 2 dm.
