A rectangle’s width is 2 meters shorter than its length, l Its area is 168 square meters. Which equation can be used to find the length of the rectangle?
Answer
A
1 half l squared is equal to 168
B
l times l plus 2 is equal to 168
C
2 l squared is equal to 168
D
l times l minus 2 is equal to 168
Explanation
The length is l meters, so the width is l − 2 meters. A rectangle’s area is length times width, giving l(l − 2) = 168. This is choice D: l times (l minus 2) equals 168.
