Question

A large room has the dimensions shown below.A partition is to be installed so that 2 classes can use it.The area of the smaller classroom is 38x. How can the area of the larger classroom be expresses in terms of x?

Answer 1

It would be D because you need to multiply 38 and 50. But x is the length of one classroom, and because we don't know it, you would get 38(50-x).

Good luck!!
