your answer would be 147 square feet!!
this is because if you break the composite figure into two rectangles, they would be
rectangle 1:
7 (width) x 13.5 (height) = 94.5 sq ft
rectangle 2:
15 (width) x 3.5 (height) = 52.5 sq ft
then, when you add both areas,
94.5 + 52.5
the total area is,
= 147 square feet
