Question

the ratio of the length of a vertical pole and its shadow on the ground is 7:2. find the length of the pole if the length of the shadow is 2.4 m

Answer 1

let length of the pole=l,

A.T.Q

l/2.4 = 7/2,

l=7×2.4/2,

l=7×1.2,

l=8.4 me

Answer 2

First, we put all the values into ratio form.

Length of pole : Shadow on ground

7 : 2

x : 2.4m

*Let the length of the pole be x.

As we can see, to change the ratio of 2 into 2.4m, 2 is multiplied by 1.2. Hence, we multiply the ratio of 7 with 1.2 to find x.

7 × 1.2 = 8.4m

Therefore, the length of the pole is 8.4m.
