Question

28. Area of a parallelogram is 28 cm2. If its base is 7 cm. Find its height.​

Answer 1

h = 4cm-

Base = 7 cm

Area = 28 cm square

Answer 2

Answer :-

• The height of the parallelogram is 4 cm.

Given :-

• Area of a parallelogram = 28 cm².
• It's base = 7 cm.

To find :-

• It's height.

Step-by-step explanation :-

• In this question, the area and base of a parallelogram has been given to us. We have to find it's height.

-----------------

We know that :-

$\underline{\boxed{\sf Area \:of \:a \:parallelogram = Base \times Height}}$

Here,

• Area = 28 cm².
• Base = 7 cm.

• Let the height be h.

Hence,

$\underline{\underline{\mathfrak{Substituting \: these \: values \: in \: the \: formula,}}}$

$\longmapsto\bf 28 = 7 \times h$

Multiplying 7 by h,

$\longmapsto\bf 28 = 7h$

Transposing 7 from RHS to LHS, changing it's sign,

$\longmapsto\bf\dfrac{28}{7} = h$

Dividing 28 by 7,

$\longmapsto\overline{\boxed{\bf 4 \: cm = h}}$

-----------------

• Hence, the height of the parallelogram = 4 cm.
