Answer key · Area of a parallelogram
1. 84
Cut the triangle off one end and move it to the other: the parallelogram becomes a rectangle. Area = base × height.
The base is 14 cm and the height is 6 cm.
14 × 6 = 84 cm².
2. 120
Cut the triangle off one end and move it to the other: the parallelogram becomes a rectangle. Area = base × height.
The base is 10 cm and the height is 12 cm.
10 × 12 = 120 cm².
3. 96
Cut the triangle off one end and move it to the other: the parallelogram becomes a rectangle. Area = base × height.
The base is 16 cm and the height is 6 cm.
16 × 6 = 96 cm².
4. 204
Cut the triangle off one end and move it to the other: the parallelogram becomes a rectangle. Area = base × height.
The base is 17 cm and the height is 12 cm.
17 × 12 = 204 cm².
5. 120
Cut the triangle off one end and move it to the other: the parallelogram becomes a rectangle. Area = base × height.
The base is 15 cm and the height is 8 cm.
15 × 8 = 120 cm².
