8,000*20=160,000. it's 160,000 because 8*2=16 and there are 4 zeroes so 16+4 zeroes is 160,000

It is 160000 because 8*2 is 16 just add 0000 after the 16

Find the area of the shaded shape pls quickly

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

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 :

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

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

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