Answer: 88meters

Step-by-step explanation:

make a direct variation

so if a 2.8 meter building casts a 1.61 shadow then

2.8/1.61

and if a unknown building mark that as x gives a 50.75 shadow then

2.8/1.61=x/50.75

the you cross multiply that would give you 1.61x=142.1

then divide both sides by 1.61 you get x=88.2608696

But since it say round to the nearest meter you round to 88!
