Question

find area of the shaded region of the rectangle (please do step by step) ​

Answer 1

Area Of Shaded Region = Area of Rectangle - (area of 1st small rectangle + Area Of 2nd Small Rectangle

$\bf \: Area \: of \: Rectangle = 2(l + b) \\ = > \bf \: 2(42m \: + \: 35m) \\ \bf = > \: 84m \: + \: 70m \\ = > \bf \: 154m$

$\bf \: Area \: of \: 1st \: small \: Rectangle = 2(l + b) \\ = > \bf \: 2(19m \: + \:10m ) \\ \bf = > \: 38m \: + \:20m \\ = > \bf \: 58m$

$\bf \: Area \: of \: Rectangle = 2(l + b) \\ = > \bf \: 2(15m \: + \:8m) \\ \bf = > \: 30m \: + \: 16m \\ = > \bf \: 46m$

Area Of Shaded Region = Area of Rectangle - (area of 1st small rectangle + Area Of 2nd Small Rectangle

= 154m - (58m + 46m)

= 154m - 104m

= 50m
