Question

When the sun is at a certain angle in the sky, a 50 foot building will cast a 20 foot shadow. What is the length of the shadow in feet cast by a 20 foot pole at the same time?

Answer 1

Prepara a bar graph. (Mention the scale)

Potato= 25 per kg

Tomato= 40 per kg

Cauliflower= 10 per kg

Chilli= 15 per kg

Lemon= 30 per kg

Answer 2

8 ft

Explanation:

The height of the building/pole and shadow of each are in proportion.

let x be the length of shadow of the pole, then

`(50)/(20)` =
`(20)/(x)` ( cross- multiply )

50x = 400 ( divide both sides by 50 )

x = 8

The shadow cast by the pole is 8 ft
