Look at the attachment. The idea is to "divide and conquer." That is, to divided the given figure into rectangular regions, find the area of each, and then add them together.

Answer 7

The area of a rectangle is length times width so the red rectangle is 4*1 or 4 square yards in area.

@desfields901 The blue rectangle has dimensions 3 by 4. So, what is its area?
