Answer:
47 meters
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one. Please have a look at the attached photo.
My answer:
Given
- The building is about 2150 square meters
- The height of the building: 25 meters
As we know, the formula to find the area of a parallelogram is:
A = the base* the height
=> the base in this question is:
= The area / the height
= 2150 / 25 = 86 meters
As we can see in the photo, x + 39 meters = the base
=> x = the base - 39 meters
= 86 meters - 39 meters
= 47 meters
