Question

The length of the rectangle exceeds its breadth by 3 cm. If the length and breadth are each increased by 2 cm, then the area of new rectangle will be 70 sq. cm more than that of the given rectangle. Find the length and breadth of the given rectangle.

Answer 1

Answer:

270 sq.cm

Step-by-step explanation:

let breadth of rectangle be x

given, length= x+3

area=x(x+3)=x2+3x

when length and breadth are each increased by 2,

breadth=x+2

length=x+3+2=x+5

given, area =70 sq.cm

x2+7x+10=70+x2+3x

x2+7x-x2-3x=70-10

7x-3x=60

4x=60

x=60/4

x=15

area of given rectangle=x(x+3)

                                              =15(15+3)

                                              =15(18)

       area of given rectangle=270 sq.cm
