Find the missing values:
S. No. | Base | Height | Area of the Parallelogram |
(a) | 20 cm | 246 cm2 | |
(b) | 15 cm | 154.5 cm2 | |
(c) | 8.4 cm | 48.72 cm2 | |
(d) | 15.6 cm | 16.38 cm2 |
(a) It is given in the question that,
Height of parallelogram = h
Base of parallelogram = 20 cm
Area of parallelogram = 246 cm2
We know that,
Area of parallelogram = Base × Height
246 = 7 × 4
⇒ h = 12.3 cm
∴ Height of parallelogram is 12.3 cm
(b) It is given in the question that,
Height of parallelogram = 15 cm
Base of parallelogram = b
Area of parallelogram = 154.5 cm2
We know that,
Area of parallelogram = Base × Height
154.5 = b × 15
b = 
= 10.3 cm
∴ Base of parallelogram is 10.3 cm
(c) It is given in the question that,
Height of parallelogram = 8.4 cm
Base of parallelogram = b
Area of parallelogram = 48.72 cm2
We know that,
Area of parallelogram = Base × Height
48.72 = b × 8.4
b = 
= 5.8 cm
∴ Base of parallelogram is 5.8 cm
(d) It is given in the question that,
Height of parallelogram = h
Base of parallelogram = 15.6 cm
Area of parallelogram = 16.38 cm2
We know that,
Area of parallelogram = Base × Height
16.38 = 15.6 × h
h = 
= 1.05 cm
∴ Height of parallelogram is 1.05 cm
