Question

4. The area of a square field is 100 acres. Find its perimeter.

Answer 1

Perimeter of a square = 40 acres

Explanation:

Given the following data;

Area of square = 100 acres

The area of a square is given by the formula;

Area of square = l²

Where: l is the length of its sides.

100 = l²

Taking the square root of both sides, we have;

l = 10 acres

Now to find the perimeter;

Perimeter of a square = 4 * length of sides

Perimeter of a square = 4 * 10

Perimeter of a square = 40 acres
