Answer 2

The height of building=24 m

Step-by-step explanation:

Height of flagpole=h=8 m

Length of shadow of flagpole=l=10 m

Length of shadow of building=l'=30 m

Let h' be the height of building.

Two triangles are similar

When two triangles area similar then the ratio of their corresponding sides are equal

Therefore, $\frac{h}{h'}=\frac{l}{l'}$

$\frac{8}{h'}=\frac{10}{30}$

$h'=\frac{8\times 30}{10}=24 m$

Hence, the height of building=24 m
