Question

Mr. Campbell has a square garden with an area of 256 square feet. He wants to put a fence along 3 sides of the garden. How many feet of fencing will he need?

Answer 1

Explanation:

It should be noted:

Area of square garden = L² = 256

Square root both sides of the equation to find the length of the square garden. Then, use the length of the square garden to calculate the length of fence required for 3 sides of the garden.

Square root both sides.

√L² = √256

=> L = 16

Multiply the length by 3.

3L = 16 x 3 = 48 feet

Thus, Mr. Campbell will need 48 feet of fencing.
