Answer 1

Answer:

Answer will be 75 m

Step-by-step explanation:

Length of the ground : Width of the ground = 5:2

Width = 30 m

Let the length of the school ground be x

To find the length we have to : -

5:2 = x : 30

=> Product of extremes = Product of means

=> 5×30 = 2x

=> x = 150 ÷ 2

=> x = 75

In this sum extremes means the first and the fourth terms and means are the second and the third terms .
