Question

The perimeter of a rectangular garden is 43.8 feet. Its length is 12.4 feet. What is the width

Answer 1

The width is 9.5.

First you know what the length is. You must find the measurement of both combined.
12.4 x 2 = 24.8 (Length)

Subtract this number from the perimeter. 43.8 - 24.8 = 19.

19 is your width multiplied by two. The total measurement of both, to find just the width divide by 2.

19 / 2 = 9.5 (WIDTH)

Answer 2

perimeter of rectangle =2(l+b)

43.8 =2(12.4 + w)

21.9=12.4 +w

21.9-12.4 = w

w=9.5 feet
