Question

. If the length of a rectangle is decreased
by 2 metres and the breadth increased
by 2 metres the are would inc rease
8 square metres. if the length is decreased
by 3 metes and the breadth decreased by 1 metre
. the area would decrease by 27square centimeters. what are the length and breadth
​

Answer 1

Answer:

first convert cm into m in second equation

Step-by-step explanation:

let length be x

and breadth be y

:-area is x*y =xy

ATQ

(x-2)(y+2)=xy+8

(x-3)(y-1)=xy-0.27

solving both equations

2x-2y=12

-x-3y= - 3.27

subtracting both equations

multiply first equation with 3 and second equation with 2

x=5.32

y=0.68
