Question

find the area of the shaded region in the following figure:-​

Answer 1

Answer:

278

Step-by-step explanation:

let the rectangle be ABCD

so,area of abcd 57m×43m=2451

now,let the inner rec.be efgh so area of efgh

length of ef =57-(2+2)=53

breadth of eh=43-(1+1)=41

so,area of inner rectangle efgh =2173

so,area of shaded region =(abcd-efgh)

2451-2173=278

Answer 2

well subtract big rectangle area from small one you'll get your answer like

43×57-42×53

you'll solve further to get your answer ❤️
