Question

The width of a rectangle is 14 its length. The perimeter of the rectangle is 360 ft. What is the length, in feet, of the rectangle?a. L=36 b. L=144 c.L=90 d. L=160

Answer 1

Solution

For this case we know the width = 14ft

We also know the perimeter given by P= 360 ft

The formula for the perimeter is given by:

P= 2w + 2l

Where P = perimeter, w = width, h = lenght

Then we can solve for the lenght and we got:

2l = P -2w

2l = 360 -2*14

2l= 332

l = 332/2 = 166

On this case the most accurate solution seems to be:

d. L=160​
