Answer 1

Answer:

GIVEN:-

ABCD is a rectangle

with length (AB) = 20 CM

breadth (BC) = 15 CM

And

Triangle AED

Base (AD)= 15 CM

Height (FE) = 10 CM

Solution

$\tt \: Total \: \: Area \: \: of \: \: figure = length \times beadth \\ = 20 \times 15 \\ \tt = 300 \: {cm}^{2}$

$\tt \: Area \: \: of \: \: triangle = \frac{1}{2} \times base \times height$

$\tt \: Area \: \: of \: \: triangle = \frac{1}{2} \times base \times height \\ \\ \tt \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{1}{2} \times 15 \times 10 \\ \\ \tt \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 75 \: {cm}^{2}$

$\tt \: Area \: \: of \: \: shaded \: \: region = 300 - 75 \\ \tt \: = 225 \: {cm}^{2}$

Hope it will help you.
