The area of a rectangle is L x W, so 9(5+x) is the formula for the area in factored form. It can be simplified to 45+9x
Answer:
The top one is 135 cm^2
Step-by-step explanation:
To find the area, all you need to do is multiply the 3 different measurements. For the one in the top corner we need to multiply the length by the width by the height. The work is done below for you on that one.
A = l * w * h
A = 15 * 3 * 3
A = 135 cm^2
