If the gym is a square with 17 meters sides, its area is given (as any other square) by the square of the side:
So, the area of the classroom is
We can deduce the side of the classroom only assuming that it is a square as well: if this is the case, the side of a square with given area is the square root of the area, so we have
Answer:
The distance of the side of the picture from the edge of the wall is 8.5 inches
Step-by-step explanation:
see the attached figure to better understand the problem
Let
x -----> distance of the side of the picture from the edge of the wall
we know that
The wide of the wall must be equal to the wide of the picture plus two times the distance of the side of the picture from the edge of the wall
so
The linear equation that represent this situation is
solve for x
therefore
The distance of the side of the picture from the edge of the wall is 8.5 inches
