1. Find the area. The figure is not drawn to scale.

arlik [135]

Answer-

1- D. 13.6 cm²

2- A. 4.4 cm²

Solution-

We know that,

$\text{Area}= \frac{1}{2}\times \text{Base}\times \text{Height}$

Here,

Base = 3.4 cm

Height = 8 cm

Applying the formula,

$\text{Area}= \frac{1}{2}\times 3.4\times 8 = 13.6\ cm^2$

Here,

Base = 4.4 cm

Height = 2 cm

Applying the formula,

$\text{Area}= \frac{1}{2}\times 4.4\times 2 = 4.4\ cm^2$

5 divided by 3.14 = 5/3.14 = 500/314 so it is rational as well.
