Question

Find the area of the adjoining figure of the given figure

Answer 1

Answer:

150cm square is area.......

Answer 2

Quadilateral PQRS is a Trapezium

Area of trapezium = ½ × (sum of parallel sides) × height

A = ½ × (18+20) × 4

$A = \frac{38 \times 4}{2} \\ \\ A = 38 \times 2 \\ \\ \boxed{A = 76 {cm}^{2} }$

_______________________________

SRT is a ∆

Area of triangle = ½ × base × height

A= ½ × 18 × 5

$A = \frac{18 \times 5}{2} \\ \\ A = {9 \times 5} \\ \\ \boxed{ A = 45 {cm}^{2} }$

_______________________________

Area of figure = Area of trapezium PQRS + Area of ∆SRT

⇒76cm² + 45cm²

$\huge\boxed{A = 121 {cm}^{2} }$
