Question

Given three side lengths of a rectangle—1 foot, 1.5 feet, and 12 inches—what is the length of the fourth side, in inches?(1 point)

Answer 1

To find the length of the fourth side of the rectangle, we need to first convert all given side lengths to the same unit, either feet or inches.

The side lengths given are:
- 1 foot
- 1.5 feet
- 12 inches

Since 1 foot is equivalent to 12 inches, we can convert the lengths to inches:
- 1 foot = 12 inches
- 1.5 feet = 1.5 × 12 = 18 inches
- 12 inches = 12 inches

Now, we have:
- Side 1: 12 inches
- Side 2: 18 inches
- Side 3: 12 inches (already in inches)

In a rectangle, opposite sides are equal. Since we have sides of 12 inches and 18 inches, each pair of opposite sides will match.

So, if we have one side of 18 inches, the opposite side must also be 18 inches, and if we have one side of 12 inches, the opposite side must also be 12 inches.

If we've already identified two sides (12 inches and 18 inches), the fourth side (the side we need to find) should match one of these values. Therefore, the fourth side must also be 12 inches (the same as the other 12-inch side).

Thus, the length of the fourth side is **12 inches**.
