The perimeter of the rectangle below is 56 units. Find the length of side
PQ.
To find the length of side PQ, we need more information about the rectangle. Specifically, we need either the length or the width of the rectangle.
To find the length of side PQ, we need to use the formula for the perimeter of a rectangle.
The formula for the perimeter of a rectangle is:
Perimeter = 2 * (Length + Width)
Given that the perimeter is 56 units, we can set up the equation as:
56 = 2 * (Length + Width)
We also know that PQ is a side of the rectangle, which means it is either the length or the width. Let's assume that PQ is the length.
So, let's set up a general equation using variables:
56 = 2 * (Length + Width)
Let's substitute PQ for Length:
56 = 2 * (PQ + Width)
Now, we need to isolate the variable PQ. Start by dividing both sides of the equation by 2:
56 / 2 = PQ + Width
Then, simplify the equation:
28 = PQ + Width
Since we assumed that PQ is the length, we can rewrite the equation as:
28 = PQ + Width
Now, we can isolate the variable PQ by subtracting Width from both sides of the equation:
28 - Width = PQ
Therefore, the length of side PQ is 28 - Width.
Note that without any specific information about the width, we cannot determine the exact length of side PQ. We can only express the length of PQ in terms of the width.
