Question

The ratio of the length of a school ground to its width is 5 : 2. Find the length of the ground if the width of the ground is 30 m.

​

Answer 1

Answer:

Step-by-step explanation:

length=5x

breadth=2x

width=40mtr

width=2×20=40mtr

so,in same way length

=5×20=100mtr

Answer 2

Answer:

Therefore, The length of the ground is 75m.

Step-by-step explanation:

In the context to the question we have to find the length of the ground;

Given;

Ratio of length to width = 5:2

width of the ground = 30 m

let the length of the ground be "l"

as we know the ratio; it it nothing but the simplest form of ratio of actual length and width

therefore ;we can say

5:2 = l :30

5/2 = l /30

l = (30 x 5) / 2

l = 150/2

l = 75m

Therefore, The length of the ground is 75m.
