Question

The areas of figure 1 (in $c{m}^2$​) and figure 2 (in $c{m}^2$​) are __ and __ respectively.

• A. 21
• B. 21
• C. $41c{m}^2$, $41c{m}^2$
• D. $31c{m}^2$, $35c{m}^2$

Answer 1

The correct option is A

21

Area of trapezium = h $\frac{(a+b)}{2}$sq. units

= $\frac{1}{2}$ $\times$ (8 + 6) $\times$ 3 = 21 $c{m}^2$

Area of triangle = $\frac{1}{2}$ $\times$ b $\times$ h = $\frac{1}{2}$ $\times$ 14 $\times$ 3 = 21 $c{m}^2$
