Here are the step-by-step solutions for each problem on the worksheet.
1. Rectangle Perimeter
*
Shape: Rectangle
*
Sides: Length = 9 ft, Width = 5 ft
*
Formula: Add all four sides together (Length + Width + Length + Width).
*
Calculation: $9 + 5 + 9 + 5 = 28$
*
Answer: 28 ft
2. Triangle Perimeter
*
Shape: Triangle
*
Sides: 7 mm, 7 mm, 6 mm
*
Formula: Add all three sides together.
*
Calculation: $7 + 7 + 6 = 20$
*
Answer: 20 mm
3. Square Perimeter
*
Shape: Square
*
Side: 8 mm
*
Formula: Since all 4 sides are equal, you can multiply one side by 4 ($8 \times 4$) or add them up ($8 + 8 + 8 + 8$).
*
Calculation: $8 \times 4 = 32$
*
Answer: 32 mm
4. Parallelogram Perimeter
*
Shape: Parallelogram
*
Sides: Top/Bottom = 8 in, Left/Right = 4 in
*
Formula: Add all four sides together. Opposite sides are equal.
*
Calculation: $8 + 4 + 8 + 4 = 24$
*
Answer: 24 in
5. Square Area
*
Shape: Square
*
Side: 4 in
*
Formula: Multiply the side length by itself (Side $\times$ Side).
*
Calculation: $4 \times 4 = 16$
*
Answer: 16 sq in (or $in^2$)
6. Rectangle Area
*
Shape: Rectangle
*
Sides: Length = 8 ft, Width = 3 ft
*
Formula: Multiply Length $\times$ Width.
*
Calculation: $8 \times 3 = 24$
*
Answer: 24 sq ft (or $ft^2$)
7. Rectangle Area
*
Shape: Rectangle
*
Sides: Length = 3 mm, Width = 1 mm
*
Formula: Multiply Length $\times$ Width.
*
Calculation: $3 \times 1 = 3$
*
Answer: 3 sq mm (or $mm^2$)
