The Wilsons want to put outdoor carpet on their porch.

How much carpet will be needed for their porch?

108 square feet

Step-by-step explanation:

This question is essentially asking us for the area. (Don't be fooled into thinking this is a perimeter question. Imagine if you had a floor with just a ring of carpet on the edges!)

Let's separate this into areas we can understand. The square to the right, with dimensions 6 ft by 6ft, has an area of

A = s*s = 6*6 = 36 square feet

The rectangle that we have left has dimensions 12 ft by 6 ft, so it has an area of

A = l*w = 12*6 = 72 square feet

Add those together to get the total area.

A(rect) + A(square) = 72 + 36 = 108 square feet

ou would have 12 of each
