Question

the length of a rectangle is greater than its breadth by 3 metre if it's area is 10 square metre find its perimeter
​

Answer 1

Answer:

the length and breadth are unequal,we can consider it to be a rectangle. so the perimeter=2( length + breath)= 2(10+7) =34m......

Step-by-step explanation:

do follow and thank

Answer 2

taking breadth as x

area=length*breadth=10m^2 (given)

so x+3 (x)=10

x^2+3x-10=0

By splitting the middle term method,

x=2

perimeter= 2 (l+b)

=2 ([2+3]+2)

=2 (7)

=14m
