Question

A building that is 300 m

tall casts a 270 m
shadow. At the same
time, a different building
casts an 90 m shadow.
How tall is the building?

Answer 1

10m

Explanation:

we can use the cross multiply method.

300m = 270m

x m = 90m

270x = 300 x 90

270x = 2700

x = 10

so the buliding is 10m tall
