Question

A rectangle has an area of 24m². its length is 5m longer than the width.

write an expression for the rectangle's length

Answer 1

2x+2(x+5)) = 24

Explanation:

2x+ 2(x+5) = 24

x is represented by the shorter side. Multiply by 2 because of the 2 sides. For the longer side, since it is 5m longer than the shorter side, you have to write (x+5). Multiply by 2 because of the 2 sides. Finally, add them both together since it is the area and set it equal to 24.
