Question

side of a square are increased by 5cm ratio of perimeter of new square and given square is 3:2. find perimeter of new square​

Answer 1

Answer:

60cm

Step-by-step explanation:

let the side of the original square be x.

perimeter of given square=4*side=4x

perimeter of new square=4(x+5)=4x+20

4x+20/4x=3/2

8x+40=12x      ( by cross multiplication)

12x-8x=40

4x=40

x=10cm

perimeter of new square=4x+20=4(10)+20

                                         =60cm
