Question

Area of the shaded portion is _________.

• A. $100c{m}^2$
• B. $110c{m}^2$
• C. $120c{m}^2$
• D. $125c{m}^2$

Answer 1

The correct option is B $110c{m}^2$

Area of shaded region $=$ Area of rectangle $-$ Area of both triangles

A${}_1=$ Area of rectangle $=180c{m}^2$

A${}_2=$ Area of triangle $△AFE=30c{m}^2$

A${}_3=$ Area of triangle $△CBE=40c{m}^2$

Area of shaded region $=180-30-40=110c{m}^2$
