Question

Find the area of quadrilateral pqrs are given in fig
​

Answer 1

$\huge \underbrace \mathfrak \pink{Answer}$

$\underline\bold\red {Area\:of\:triangle\:PSR}$

$= \frac{1}{2} \times b \times h \\ = \frac{1}{2} \times 12 \times 4 \\ = 24cm {}^{2}$

$\underline\bold\red {Area\:of\:triangle\:PQR}$

$= \frac{1}{2} \times b \times h \\ \frac{1}{2} \times 12 \times 8 \\ = 48 {cm}^{2}$

$\underline\bold\red {Area\:of\:quadrilateral\:=Area\:of\:Triangle\:PSR\:+Area\:of\:triangle\:PQR}$

$24+48=72{cm}^{2}$
