Question

A rectangle has sides measuring `(4x +5)` units and `(3x+10)` units. What is its area?

Answer 1

The area is just length times width: `(4x+5)(3x+10) = 12x^2+55x+50`

Answer 2

`12x^2+55x+50`

Explanation:

the area of a rectangle is: A=length . width
`(4x+5)*(3x+10)`
`=12x^2+40x+15x+50`
`=12x^2+55x+50`
