Question

Mrs drew wants to build a square sandbox with an area of 169 square feet. What is the total length of wood mrs. Drew needs to make the sides of the​ sandbox

Answer 1

Area of sandbox = 169 square feet

Area of square with side 'x' is given by the formula = $x^2$

We have to determine the total length of wood Drew needs to make the sides of the​ sandbox.

Total length of wood required would be equal to perimeter of sandbox.

Let 'a' be the side of the square sandbox.

So, Area of sandbox = 169

$a^2 = 169$

$a = \sqr{169}$

a = 13 feet

Total length of wood required to make sides of the sandbox = Perimeter of the square sandbox = $4 \times a$

= $4 \times 13$

= 52 feet.

Therefore, 52 feet of wood is required to make the sides of the square sandbox.
