The difference in height of the buildren and its shadow length = 5 meters
Explanation:shadow of building = 20 meters
let the height of the building = x meters
Height of a woman= 1.8 meters
Shadow of the woman = 2.4meters
We make a ratio to find the height of the building:
height of the building/shadow of building = Height of a woman/Shadow of the woman
x/20 = 1.8/2.4
cross multiply:
2.4(x) = 1.8(20)
2.4x = 36
Divide both sides by 2.4:
2.4x/2.4 = 36/2.4
x = 15 meters
Hence, the height of the building = 15 meters
The difference in height of the building and its shadow length = shadow length of the building - height of building
= 20 - 15
The difference in height of the buildren and its shadow length = 5 meters
