The perimeter of a rectangle is 162 ft. The lenght is 3 more than twice the width. How do you find the dimensions of the rectangle?
1 Answer
Width:
Length:
Explanation:
Let the length be
Let the width be
#l = 2w + 3#
#2(l+w) = 162#
#2w + 3 + w = 162/2#
#3w + 3 =81#
#3w = 78#
#w = "26 ft"#
This means that
#l = 2w + 3#
#l = 2(26) + 3#
#l = "55 ft"#
