Question

Find the area of the shapes that form the windmill given below.

• A. 50 square units
• B. 51 square units
• C. 52 square units
• D. 54 square units

Answer 1

The correct option is B 51 square units

Area of the windmill = Area of the 4 triangles + Area of the rectangle + Area of the square

Area of the triangle
$=\frac{1}{2}\times Base\times Height$
$Areaofthetriangle=\frac{1}{2}\times 3\times 4$
$=6$ square units

Area of 4 triangles = $6\times 4$
= 24 square units

Area of the rectangle = Length × Width
= $5\times 1$
= 5 square units

Area of the square = Side × Side
= $4\times 4$
= 16 square units

Area of the shapes that form the windmill = 6 + 24 + 5 + 16
= 51 square units
