Question

find the area of the shaded portion?

Plz help me Chapter Perimeter and Area​

Answer 1

both are rectangular in shape

area of rectangle=l*b

•shaded portion can be founded by subtracting area of bigger rectangle-area of smaller rectangle

area of shaded portion - area of big rectangle-area of small rectangle

60*40-5*2

2400-10m^2

2390m^2

Answer 2

HEY DUDE STEPWISE EXPLANATION IS HERE...

IF YOU WANT TO FIND AREA OF SHADED PORTION THEN ,

FIRST YOU HAVE TO CALCULATE AREA OF OUTER RECTANGLE..

WHICH IS EQUAL TO =

$l \times b$

=

$40 \times 60$

=

$2400 {m}^{2}$

NOW FIND AREA OF INNER RECTANGLE..

WHICH IS EQUAL TO=

$l \times b$

=

$5 \times 2$

=

$10 {m}^{2}$

NOW AREA OF SHADED PORTION IS EQUAL TO =

(AREA OF OUTER RECTANGLE) - ( AREA OF INNER RECTANGLE )

= (2400 - 10)m²

=

$2390 {m}^{2}$

HOPE IT HELPS...
