Given:

Height of man = 6 ft

Height of man's shadow = 11 feet

Height of building's shadow = 139 feet

To find:

The height of the building.

Solution:

We know that the heights of the objects and there shadows are always proportional.

\dfrac{\text{Height of man}}{\text{Height of man's shadow}}=\dfrac{\text{Height of the building}}{\text{Height of building's shadow}}

Let x be the height of the building.

\dfrac{6}{11}=\dfrac{x}{139}

Multiply both sides by 139.

\dfrac{6}{11}\times 139=x

\dfrac{834}{11}=x

75.8181...=x

x\approx 75.8

Therefore, the building is 75.8 feet long.

Tell whether the statement is true or false. If w is 25% of Z, then Z:W is 75:25
melamori03 [73]
False.
If w is 25% of z, then w:z would be 25:100, because 25 is 25% of 100.
If Z:W was 75:25, it would be wrong because 25 is 33% of 75, not 25%.
