Question:
The area of a rectangle of length x is given by 3x^2+5x. Find the width of the rectangle.
Answer:

Area of a rectangle is given by the formula,
Area = length * width

Here,
Area = +3x%5E2+%2B+5x+
Length = x
Here we need to find out the width.

Plug the given values in the formula.....

==> x * width = +3x%5E2+%2B+5x+

Divide both sides by x...

==> (x * width ) /x = +%283x%5E2+%2B+5x%29%2Fx+

==> width = +3x%5E2%2Fx+%2B+5x%2Fx+


==> width = 3x + 5

Hence the answer.

Hope you found the explanation useful....

Warm Regards.
