Question

A vertical row of trees 12m long casts a shadow 8m long on the ground At the same time a ower casts the shadow 40m long on the ground
1 Determine the height of the tower​

Answer 1

Answer:

60 m

Step-by-step explanation:

Let height of tower be x

This is a case of direct proportion

Height                           Shadow

12 m                                 8 m

 x                                     40 m

Cross- multiply.

12 X 40 = 8 X x

12 X 40 = 8x

480       = 8x

x            = 480 / 8

x = 60 m

Therefore , Height of the tower = 60 meters

Answer 2

The height of the tower​ is 60 m

Step-by-step explanation:

We are given that A vertical row of trees 12m long casts a shadow 8m long on the ground

Let the height of tower be x

Length of shadow of tower is 40m

ATQ

$\frac{12}{8}=\frac{x}{40}\\\frac{12 \times 40}{8}=x\\60=x$

Hence The height of the tower​ is 60 m
