A rectangle has width represented by x and length represented by 4x If the area of the rectangle is 80 find the value of x What is x?

length is 4x and width is x:
4x*x = 80
4x2 = 80
Divide both sides by 4:
x2 = 20
Square root both sides:
x = 4.472135955

How does increasing the dimensions of a rectangle impact the perimeter?
If you increase the rectangle's length by a value, its perimeter increases by twice that value. If you increase the rectangle's width by a value, its perimeter increases by twice that value. (A rectangle is defined by its length and width, and opposite sides of a rectangle are the same length. The lines always meet at their endpoints at 90° angles.)

The area of a rectangle is 48 square feet the length is 2 feet longer than the width what is the width of the rectangle?
The area of the rectangle is the length multiplied by the width. Also, the length is 2 feet longer than the width. Next, make the length represented by the variable l and the width represented by the variable w to make a few equations. lw=48 l=w+2 also written as l-w=2 After taking a variable away and then substituting the known variable back in, you get the length of the retangle as 8 and the width as 6.
