Question

Tristán wants to build a square garden in his backyard if the garden is going to be 64 ft2 how many feet of material will he need for the perimeter of the garden

Answer 1

Tristan will need 32 feet of material for the perimeter of the garden.

Explanation:

Given that

Area of square garden = A = 64 square feet

Perimeter = P = ?

We know that for calculation of perimeter, length of side of square is required which is not directly given in the question. The area will be used to calculate length of side and then length will be used to calculate the perimeter.

So,

`Area = A = s^2`

s is for side

Putting the value of area

`64 = a^2`

Taking square root on both sides

`√(s^2) = √(64)\\s = 8\ feet`

The length of side is 8 feet.

Perimeter will be:

`P = 4*s\\P = 4*8\\P = 32\ feet`

Hence,

Tristan will need 32 feet of material for the perimeter of the garden.
