Question

The ratio of a flower bed to its width which is 4:7 and its perimeter is 330 cm.What is the length of the flower bed?Please answer it ASAP...

Answer 1

Ratio is 4:7

Perimeter is 330cm

Perimeter =2(l+w)

330=2(x+7x)

16x=330

X=330/16

X=20.62cm

Answer 2

Lenght=4x
Bredth=7x

Perimeter= 2 ( l + b )
=> 330 cm = 2( 4x + 7x )
=> 330cm = 2 ( 11x )
=> 330cm = 22x
=> 330cm/22=x
=> 30cm /2 = x
=> 15 cm = x

So...lenght =7x = 15 cm * 7 = 105 cm
