Question

The length of a rectangle exceeds its breadth by 4 cm .if the length and breadth both are increased by 3cm,the area will be 81cmsquare more than that of the given rectangle find the length and breadth of the given rectangle.

Answer 1

Answer:

l= 8.57cm

Step-by-step explanation:

let the length be x

breadth=4 cm

we know

area = l * b

from question

81=(x+3)*(4+3)

81=(x+3)*7

81=7x+21

81-21=7x

60=7x

60/7=x

x =8.5

so length =x =8.5 cm

Answer 2

the given question means that length is four more than the breadth.....
