Find the area of the following parallelograms:
(a) 
(b) 
(c) 
(d) 
(e) 
(a) It is given in the question that,
Height of parallelogram = 4 cm
Base of parallelogram = 7 cm
We know that,
Area of parallelogram = Base × Height
= 7 × 4
= 28 cm2
∴ Area of parallelogram is 28 cm2
(b) It is given in the question that,
Height of parallelogram = 3 cm
Base of parallelogram = 5 cm
We know that,
Area of parallelogram = Base × Height
= 5 × 3
= 15 cm2
∴ Area of parallelogram is 15 cm2
(c) It is given in the question that,
Height of parallelogram = 3.5 cm
Base of parallelogram = 2.5 cm
We know that,
Area of parallelogram = Base × Height
= 2.5 × 3.5
= 8.75 cm2
∴ Area of parallelogram is 8.75 cm2
(d) It is given in the question that,
Height of parallelogram = 4.8 cm
Base of parallelogram = 5 cm
We know that,
Area of parallelogram = Base × Height
= 4.8 × 5
= 24 cm2
∴ Area of parallelogram is 24 cm2
(e) It is given in the question that,
Height of parallelogram = 4.4 cm
Base of parallelogram = 2 cm
We know that,
Area of parallelogram = Base × Height
= 2 × 4.4
= 8.8 cm2
∴ Area of parallelogram is 8.8 cm2
