If the area of a rectangular field is 21x2 – 7x and one of its sides is 7x, what is its other side?
Question
If the area of a rectangular field is 21x2 – 7x and one of its sides is 7x, what is its other side?
Solution
The area of a rectangle is calculated by multiplying its length by its width. In this case, we know the area (21x^2 - 7x) and one side (7x).
To find the other side, we can divide the area by the known side:
(21x^2 - 7x) / 7x
This simplifies to:
3x - 1
So, the other side of the rectangle is 3x - 1.
