\(Area \;of\; parallelogram = Base \times Height\)
(a)\( Height= 4 \;cm\)
\(Base = 7\; cm\)
\(Area\; of \;parallelogram = 7 \times 4 = 28 \;cm^2\)
(b) \(Height= 3 \;cm\)
\(Base = 5 \;cm\)
\(Area \;of \;parallelogram = 5 \times 3 = 15 \;cm^2\)
(c) \(Height= 3.5 \;cm\)
\(Base = 2.5 \;cm\)
\(Area\; of\; parallelogram = 2.5 \times 3.5 = 8.75 \;cm^2\)
(d) \(Height= 4.8 \;cm\)
\(Base = 5 \;cm\)
\(Area\; of\; parallelogram = 5 \times 4.8 = 24 \;cm^2\)
(e) \(Height= 4.4 \;cm\)
\(Base = 2 \;cm\)
\(Area\; of\; parallelogram = 2 \times 4.4 = 8.8 \;cm^2\)




| So No | Base | Height | Area of parallelogram |
|---|---|---|---|
| a. | 20 cm | - | 246 \(cm^2\) |
| b. | - | 15 cm | 154.5 \(cm^2\) |
| c. | - | 8.4 cm | 48.72 \(cm^2\) |
| d. | 15.6 cm | - | 16.38 \(cm^2\) |
