Question

The area of a rectangle is 112 units squared.

Answer 1

Answer:

Step-by-step explanation:

The area for a rectangle is A = LW. We know the area and we also know the length. We are solving for the width.

$112=7\sqrt{x}$ and

$16=\sqrt{x}$

Siince the width is given as the square root of x, and the square root of x is equal to 16, then the width is 16. Now to find the value of x from the last statement in our equation. If

$16=\sqrt{x}$ and we want to solve for x, we will square both sides, since squaring undoes a square root. Since this is an equation, we have to square both sides.

256 = x
