Question

Find the area of the head and face of the robot given below.

• A. 15 square inches
• B. 16 square inches
• C. 24 square inches
• D. 30 square inches

Answer 1

The correct option is D 30 square inches

Area of the robot's head = Area of the triangle

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

Area of the robot's face
= Area of Rectangle A
= Length × Width
= $6\times 3$
= 18 square inches

Total area of the head and face
= Area of 2 yellow triangles + Area of Rectangle A
= $6\times 2+18$
= 30 square inches
