Question

the ratio of length and breadth are in the ratio 2 ratio 5 its area is 6300 find its perimeter​

Answer 1

Answer:

ratio=2:5

perimeter of rectangle =2×(L+B)

L=2x ; B=5x

so,

2×(2x+5x)=6300

=2×(7x)=6300

=7x=6300/2

= 7x=3,150

= x=3150/7

=x= 450

Now,

2×x=length

2×450=900

5×x=Breadth

5×450=2250

2×(900+2250)=6,300
