Question

help me find the area of this quadrilateral with workings pls​

Answer 1

Answer:

$59.2389 {m}^{3}$

Step-by-step explanation:

Area of quadrilateral PQRS = Area of ∆ PRS + Area of ∆ PQR

$area \: of \: a \: triangle = \frac{1}{2} \times (base) \times (height)$

$\frac{1}{2} \times 9.2 \times 8.28 + \frac{1}{2} \times 6.62 \times 6.39$

$= 38.088 + 21.1509$

$= 59.2389 {m}^{3}$
