Question
Find the missing value:
| Base | Height | Area of parallelogram |
| ______ | 15 cm | 154.5 cm2 |
Solution
| Base | Height | Area of parallelogram |
| 10.3 | 15 cm | 154.5 cm2 |
Explanation:
b = ?
h = 15 cm
Area = 154.5 cm2
b × 15 = 154.5
b = `154.5/15`
b = 10.3 cm
Therefore, the base of such parallelogram is 10.3 cm.
