Question

The area of given figure is:
Note : All measurements are in millimetres

• A. 41 sq. units
• B. 42 sq. units
• C. 24 sq. units
• D. 40 sq. units

Answer 1

The correct option is B

42 sq. units

Area of the figure = Area of A + Area of B + Area of C

Area of rectangle = $length\times breadth$

A , B & C are rectangles
= $3\times 6$ + $4\times 3$ + $2\times 6$
= $18+12+12$
= $42m{m}^2$ (we know $1mm={10}^{-1}cm$)

= $42\times {10}^{-2}c{m}^2$
