Question

The perimeters of two squares in the model are given. Find the perimeter of the third square. P=12 units p=16 units ​

Answer 1

20 units

Explanation:

Answer 2

20 units

Explanation:

1) find the side of the first square

side = P / 4 = 12:4 = 3 units

2) find the side of the second square

side = P / 4 = 16 : 4 = 4 units

3) use the Pythagorean theorem to find the hypotenuse of the right triangle

`√(4^2 + 3^2) = √(16 + 9) = √(25) = 5` units

4) find the perimeter of the third square

P = side x 4 = 5 x 4 = 20 units
