To calculate the area of a parallelogram, multiply the base times '\(b\)' the height '\(h\)'.

Area of parallelogram \(A =\) \(b × h\) \(square\) \(units\).

Example:

A parallelogram has a base of \(6 m\) and \(3 m\) height, what is its area?

Let the base \(b= 6m\) and the height \(h= 3m\).

Area \(A = b × h = 6m × 3m =18m²\).

To calculate the base of the parallelogram, divide area '\(A\)' by height '\(h\)'.

Base of parallelogram \(b = A/h\) unit.

Example:

A parallelogram has an area of \(64 m²\) and its height \(4 m\), what is its base?

Let the area \(A= 64m²\) and the height \(h= 4m\).

Base \(=\) $\frac{A}{h}=\frac{64}{4}=\phantom{\rule{0.147em}{0ex}}16m$.

To calculate the height of the parallelogram, divide area '\(A\)' by base '\(b\)'.

Height of parallelogram \(h = A/b\) unit.

Example:

A parallelogram has an area of \(64 m²\) and \(16 m\) base, what is its height?

Let the area \(A= 64m²\) and the height \(h= 16m\).

Height \(=\) $\frac{A}{b}=\frac{64}{16}=\phantom{\rule{0.147em}{0ex}}\mathit{4}\phantom{\rule{0.147em}{0ex}}m$.

Where '\(A\)' is denoted as area, '\(b\)' is denoted as the base and '\(h\)' is denoted as the height.

To calculate the perimeter of a parallelogram, multiply \(2\) times the (base \(+\) side length).

Perimeter of parallelogram \(P = 2 (b + l)\).

Where '\(b\)' is denoted as the base, and '\(l\)' is denoted as the side length.

Example:

A parallelogram has a base of \(5 m\) and \(3 m\) length, what is its perimeter?

Here the base \(b= 5m\) and the side length \(l= 3m\).

Perimeter \(=2(b + l)\)

\(=2(5+3)\)

\(=2(8)\)

\(=16m\).
