the area of rectangle gets reduced by a square units if its length is reduced by 5 units and breadth is increased by 3 units if we increase the length by 3 minutes and the breadth by 2 units the area increased by 67 square units find the dimensions of the rectangle cross multiplication​

Answer»

Answer:

length is -202 and breadth is 155

Step-by-step EXPLANATION:

let the length be X and breadth be y

area=l*b=XY

(x-5)(y+3)=xy-1

xy+3x-5y-15=xy-1

3x-5y=14

(X+3)(y+2)=XY+67

xy+2x+3y+6=XY+67

2x+3y=61

3x-5y=14 (*2)

2x+3y=61 (*3)

6x-10y=28

6x-9y=183

-y=-155

y=155

2x+3y=61

2x+465=61

2x=-404

X=-202
