Question

A billboard cast a shadow of 6m. At the same time a metere stick casts a shadow of 40cm. How tall is the billboard?

Answer 1

15m

Explanation:

we know that

height(m):shadow (m)

we need to convert the cm to meters

1m: .4m

x: 6m

To solve for x just mulitply the 1 by 15 (15 because this is what we mulitplied the .4 meters to get to 6)

The answer is therefore 15m
