Given the figure of a composite shape
Part (A):
We will break the shape into smaller shapes and write the missing side lengths
The shape will be as shown in the following figure:
Part (b): we will find the total area:
The shape has 2 squares and two rectangles
The square has a side of length = 3 cm
So, the area of the 2 squares = 2 x 3 x 3 = 18 cm²
The dimensions of the smaller rectangle are: 3 cm, 5 cm
So, the area of the rectangle = 3 x 5 = 15 cm²
The dimensions of the larger rectangle are 3 cm, 7 cm
so, the area of the rectangle = 3 x 7 = 21 cm²
So, the total area of the shape = 18 + 15 + 21 = 54 cm²
So, the answer will be:
Total area = 54 cm²
