Question

Ratio of length and breadth of a rectangle is 5:3. If the area of the rectangle is 60 sq. units then perimeter of the rectangle is __________ *​

Answer 1

Answer:

let the ratio be 5x : 3x

area of rectangle = l×b

5x *3x =60

15x^2 =60

x^2=4

x =2

so length = 5×2 =10

breadth = 3× 2 =6

perimeter of rectangle = 2(l+b)= 2(10+6)=2* 16=32sq.units
