The perimeter of a rectangle is 300 ft and the length of the rectangle is 3 ft more than twice the width. Find the dimensions of the rectangle

Answer provided by our tutors

Let

l = the length of the rectangle, l>0
w = the width of the rectangle, w>0

The length of the rectangle is 3 ft more than twice the width:

l = 3 + 2w

The perimeter is 300 ft:

P = 300 ft

P = 2l + 2w

2l + 2w = 300

plug l = 3 + 2w into the last equation:

2(3 + 2w) + 2w = 300

........

w = 49 ft

l = 3 + 2*49

l = 101 ft

The dimensions of the rectangle are: the length is 101 ft and the width is 49 ft.
