Question

find the area of the shaded shape pls quickly​

Answer 1

${\qquad\qquad\huge\underline{{\sf Answer}}}$

Let's solve ~

Area of shaded region is equal to :

Area of rectangle - Area of two triangles ~

1. Area of rectangle :

$\qquad \sf  \dashrightarrow \: length \times width$

$\qquad \sf  \dashrightarrow \: 20 \times 15$

$\qquad \sf  \dashrightarrow \: 300 \: \: cm {}^{2}$

2. Area of first triangle :

$\qquad \sf  \dashrightarrow \: \cfrac{1}{2} \times (base) \times (height)$

$\qquad \sf  \dashrightarrow \: \cfrac{1}{2} \times (20 - 18) \times (15)$

$\qquad \sf  \dashrightarrow \: \cfrac{1}{2} \times (2) \times (15)$

$\qquad \sf  \dashrightarrow \: 15 \: \: cm {}^{2}$

3. Area of second triangle :

$\qquad \sf  \dashrightarrow \: \cfrac{1}{2} \times (base) \times (height)$

$\qquad \sf  \dashrightarrow \: \cfrac{1}{2} \times (6) \times(20)$

$\qquad \sf  \dashrightarrow \: 3 \times 20$

$\qquad \sf  \dashrightarrow \: 60 \: \: cm {}^{2}$

Area of shaded region is :

$\qquad \sf  \dashrightarrow \: 300 - (15 + 60)$

$\qquad \sf  \dashrightarrow \: 300 - 75$

$\qquad \sf  \dashrightarrow \: 225 \: \: cm {}^{2}$
