Question

the area of a parking lot is 2475 ft^2. The rectangular parking lot has dimensions such that the length is 10 feet longer than the width. What is the dimensions of the praking lot?

Answer 1

l=10+w
and area = l*w
= (10+w)*w
w^2+10w-2475=0

Answer 2

\[w=\frac{ -b \pm \sqrt{b^2-4ac} }{ 2a }\] b= 10, c=-2475, a=1 plug in the values
