Question

2) Find the area of the composite shape.

Answer 1

256 cm²

Explanation:

Split the shape into 2 rectangles, one to the right of the dashed line, one to the left. Calculate the 2 areas, then add them together to get the area of the composite shape.

Rectangle 1: 18 x 8 = 144

Rectangle 2: (16 - 8)(18 - 4) = 8 x 14 = 112

Total area = 144 + 112 = 256

Answer 2

area of composite shape =256cm²

Explanation:

area of composite shape =area of the two shapes

1st shape=18×8=144cm²

2nd shape=8×14=112cm²

area of composite shape =area of 1st shape + area of 2nd shape

A=144+112

A=256cm²
