Answer:
It's 4
Step-by-step explanation:
* / = square root
You simply 2/72 which is 12/2, then simplify /8 which is 2/2.
You combine 2/2 and /2 which is 3/2.
The equation should be 12/2 over 3/2 so you simplify it which will give you 4.
(By simplifying 12/2 over 3/2, you cross out /2 and convert 12 over 3 into a whole number)
Let s be the side length of the square. The dimensions of the rectangle are three times the side of the square (i.e. 3s), and two less than the side of the square (i.e. s-2).
So, the area of this rectangle is
The area of the square is , and we know that the two areas are the same, so we have
The solution s=0 would lead to the extreme case where the rectangle and the square are actually a point, so we accept the solution s=3.
