Rectangle Perimeter and Side Lengths

The video tutorial explains how to find the missing side of a rectangle given its perimeter. It starts by introducing the problem of a garden with a perimeter of 40 yards and a missing side labeled as X. The tutorial then discusses the properties of rectangles, emphasizing that opposite sides are equal. It proceeds to calculate the perimeter by adding known sides and solving for the missing side. The solution involves subtracting the sum of known sides from the total perimeter and dividing the remainder by two to find the length of the missing side, which is 11 yards.

What is the total perimeter of Daven's garden?

• 30 yards

• 40 yards

• 50 yards

• 60 yards

In a rectangle, what is true about the lengths of opposite sides?

• They are always equal.

• One side is always double the other.

• They are always half the perimeter.

• They are always different.

If one side of the rectangle is 9 yards, what is the length of the opposite side?

• 36 yards

• 18 yards

• 27 yards

• 9 yards

What is the first step in solving for the missing side of the rectangle?

• Divide the total perimeter by 2.

• Add the known sides together.

• Subtract the known sides from the total perimeter.

• Multiply the known side by 4.

After subtracting the known sides from the total perimeter, what should you do next?

• Multiply the result by 2.

• Divide the result by 2.

• Subtract the result from the known sides.

• Add the result to the known sides.

What is the length of the missing side of Daven's garden?

• 10 yards

• 12 yards

• 11 yards

• 9 yards
