Question

Area of a rectangle reduces by 20 meter square , if it's length is increased by 1m and breadth is reduced by 2m. Area increases by 12 meter square, if length is reduced by 3m and breadth is increased by 4m. Find dimensions of rectangle.

Answer 1

Answer:

Length = 15m

Breadth = 12m

Step-by-step explanation:

Let length =x

breadth =y

(x+1)(y-2)=xy-20

y-2x= -18(first eq)

(x-3)(y+4)= xy+12

4x-3y=24

On solving,

We get

Length = 15m

Breadth= 12m
