Text Book Answers for Number 10-12

10. A parallelogram-shaped stripe is going to be painted on the wall of a daycare centre. There is enough paint to make a stripe with area of 9m². How high can the stripe be?
Answer: The stripe can go up by 6 meters how did i get the answer? i divided 9÷1.5=6 so the height will be 6
here's the formula:
Area of parallelogram
Base×Height=
1.5×6=
9m²



11. a) With a ruler, measure the base and height of this parallelogram. Explain how you measured it.

Answer: Base=2cm, Height=1.5cm. I measured the base with a ruler. Then used a protractor to draw the height perpendicular to the base and measure the height using a ruler.


b) What is the area?

Answer: the area is 3cm² since 2×1.5= 3


c) Use a different side of the parallelogram as the base. Determine the new height and calculate the area. How doe this compare to your answer?

Answer: The answer will be the same.


12. Which of the 2 shapes shown below has a greater area?Explain your answer



Answer: The are is the same because the 2 shapes has the same base and height so if u calculate it with the formula the answer will be 12cm²

Here's a video to help and understand how to do area of parallelogram:
