Question

The perimeter P of a rectangle is given by the formula P = 2l + 2w, where l is the length and w is the width. If the length of the rectangle is 32 ft, and the perimeter is 94 ft, what is the width of the rectangle?

Answer 1

2l+2w=94ft

Length = 32ft

2(32)+2w=94

64+2w=94

2w=94-64
=30

2w=30

w=30/2

w=15



HOPE IT HELPS

Answer 2

w = 15

Explanation:

94 = 2(32) + 2w

(2*32)

94 = 64 +2w

(-64)

30 = 2w

(÷2)

15 = w
