Given the diagram below, find the value of x if the area of the rectangle is 78 square meters . ​

Answer 1

Answer:

x = 6

Step-by-step explanation:

You want to find factors of 78 that differ by 7. The value of x is the smaller of them.

78 = 1·78 = 2·39 = 3·26 = 6·13

We see the last factors on this list differ by 7, so we conclude x = 6.
