Question

The length of recctangle is 7/5 of is breadth.it is perimeter is 48cm,then what is length

Answer 1

Let the breadth be x

=length =7/5x

Perimeter=2(l+b)

48=2(7/5+x)

48=2(7x+5x/5) lcm=5

48/2=12x/5

48*5/12*2 =x

10=x

Breadth =10

Length =7/5*10

=14

Therefore.. Length =14cm..hope it suits you
