You want to determine the height of your school. The building casts a 6 foot shadow at the same time you cast a 15 inch shadow. If you are 5 feet tall how tall is the building?

Cross multiply and solve for x.

x/6 = 5/1.25

use ratio, remember to have same units

let the height of building be h ft
h/6 = 60/15
h = 6(60/15) = 24

the building is 24 ft high

Well first let’s covert the ft to in- 5ft is 60 in and 6ft is 72 in. Then we want to set up 2 fractions based on height and shadow, so we have 60/15=x/72 (we put x because that’s what we’re trying to find). Then we do cross multiplication so now we have 15x=4320. We divide 15, so now we have 4320/15=288. So the building is 288 in tall or 24ft tall! Glad to help! :)
