Question

The length of a rectangle exceeds it breadth by 3 cm. If the length and breadthare each increased by 2cm, then the area ofvthe new rectangle will be 70 sq. cm more than that of the given rectangle. Find length and breadth of the given recatangle. Whoever answers first I will give them 5 stars and mark as brainliest.

Answer 1

Step-by-step explanation:

let the length and breadth of rectangle be x and y and x>y

ATQ,

x=y+3

When length and breadth increase 2 cm

(x+2)(y+2)=xy+70

(y+5)(y+2)=(y+3)y +70

y^2+7y+10=y^2 +3y +70

7y-3y=70-10

4y=60

[y=15 cm]

then

[x=18 cm]
