Question

Find the dimensions of an American football field. The length is 200 feet more than the width, and the perimeter is 1040 feet. Find the length and width?

Answer 1

Explanation:

Perimeter = 2* Length + 2* Width

1040 = 2*(X+200) +2*X

1040 = 4x +400

640 = 4x

160 = x

Width = 160

Length = 360

test: 2x 160 = 320 /// 2x 360 = 720

720+320 = 1040
