Question

the perimeter of rectangle plot is 120 M the length of a plot is decreased by 5 M and the breadth is increased by 5 M then the area increased by the 75 m square find the dimension of the rectangular plot​

Answer 1

Step-by-step explanation:

No Let the length be x and breadth be y

Perimeter =80m

2(x+y)=80m

x+y=80/2=40

x=40-y

Area=x*y

If length decreased by 2

Breadth decreased by 2

(40-y-2) (y+2)=(40-y)y+36

(38-y)(y+2)=40y-y*y+36

38y+76-y*y-2y=40y-y*y-2y+36

36y+y*y+76=40y-y*y+36

40y-36y=76-36

4y=40

Y=10

X=40-y

x=30

Length =30m

Breadth =10m

hope this will help you
