Question

*If area of a parallelogram is 20 sq cm and its base is 5 cm ,what is its height?*

Answer 1

Answer:

Area = 1/2 x base x height

20 = 1/2 x 5 x height

20 = 5/2 x height

20 x 2/5 = height

4 x 2 = height

8 cm = height

Answer 2

Answer:

$area = \frac{1}{2} \: base \times height$

$20 = \frac{1}{2} \times 5 \times \: height$

$20 = \frac{5}{2} \: \times height$

$20 \times \frac{2}{5 } = height$

$4 \times 2 = height$

$height = 8cm$
