Question

Q.10. When 4 is subtracted from length and breadth of the
rectangle, the perimeter becomes 28.' What is the mathematical
form of the statement?​

Answer 1

Answer:

it very simple just finish it.

Answer 2

Step-by-step explanation:

let length is and breadth is y

4 reduced from both length and breadth

(x-4) and (y-4)

perimeter=2(l+b). formula

2(x-4+y-4)=28

2(X+y-8)=28

2x+2y-16=28

2x+2y=28-16

2x+2y=12

X+y=12/2

X+y=6
