Answer:
The rectangle is 4 inches wide.
Explanation:
To find the area of the rectangle, we would use the equation:
where l is the length, w id the width, and A is the area.
We can rewrite this equation to solve for w by dividing both sides of the equation by l:
where l is the length, w id the width, and A is the area.
We know that the area is 28 in² and the length is 7 in. Plug 7 for l and 28 for A into the equation the equation and solve for w:
w = 28/7
Simplify.
w = 4
Remember, the width and area of the rectangle is given to us in inches and square inches, so the width must also be in inches.
The width is 4 inches.
The rectangle is 4 inches wide.
