To find the length of the rectangle, we can use the formula for the area of a rectangle: length multiplied by width. In this case, we know that the width is 14 inches and the area is 105 square inches.
Let's denote the length of the rectangle as L. We can set up the following equation:
L * 14 = 105
To solve for L, we divide both sides of the equation by 14:
L = 105 / 14
Simplifying the right side:
L = 7.5
Therefore, the length of the rectangle is 7.5 inches.
What is the length of a rectangle with width 14 in. and area 105 in.^2?

A rectangle has perimeter 74 cm and length 28 cm. What is its width?
To find the width of the rectangle, we can use the formula for the perimeter of a rectangle: 2 * (length + width). In this case, we know that the perimeter is 74 cm and the length is 28 cm.
Let's denote the width of the rectangle as W. We can set up the following equation:
2 * (28 + W) = 74
To solve for W, we first simplify the left side of the equation:
56 + 2W = 74
Next, we isolate W by subtracting 56 from both sides:
2W = 74 - 56
2W = 18
Finally, we divide both sides of the equation by 2 to solve for W:
W = 18 / 2
W= 9
Therefore, the width of the rectangle is 9 cm.

Next, we isolate W by subtracting 56 from both sides:
2W = 74 - 56
