Answer:
67 units
Step-by-step explanation:
67 units squared
First, you multiply all the combinations possible with the 3 values.
5x1.5, 5x4, 1.5x4
But there are 2 of every side so you multiply each by 2.
5x1.5x2 = 15
5x4x2 = 40
1.5x4x2 = 12
12+40+15 = 67
Given
7x + 1 = 9x - 7
9x - 7x = 1 + 7
2x = 8
x = 8 / 2
x = 4
