Answer:
1,787.75
Step-by-step explanation:
The sum of the areas of the 10 rectangles gives the surface area of the cushion:
A = 140 sq. in. + 80 sq. in. + 121 sq. in. + 2(605 sq. in.) + 22 sq. in. + 2(68.875) sq. in +19 sq. in. + 58 sq. in.
= 140 sq. in. + 80 sq. in. + 121 sq. in. + 1,210 sq. in. + 22 sq. in. + 137.75 sq. in +19 sq. in. + 58 sq. in.
= 1,787.75 sq. in.
The surface area of the cushion is 1,787.75 square inches.
