Question

Area of the given figure will be

• A. 51 ${\text{cm}}^2$
• B. 21 ${\text{cm}}^2$
• C. 45 ${\text{cm}}^2$
• D. 30 ${\text{cm}}^2$

Answer 1

The correct option is A 51 ${\text{cm}}^2$

On dividing the figure into squares and rectangles, we get
A, C, E are squares measuring 3cm in length.
B, D are rectangles measuring 4 cm in length and 3 cm in breadth.

The area of figure is sum of areas of all rectangles and squares.
=(3 x 3) + ( 3 x 3 ) + (3 x 3 ) + (3 x 4 ) + ( 3 x 4 )
= 9 + 9 + 9 + 12 + 12 = 51 ${\text{cm}}^2$
