Area of parallelogram is B*H i.e. Base multiplied by Height.

Area of Triangle is 1/2B*H i.e. Half base multiplied by height.

{opposite sides of a parllelograms are equal}

Area = base x corresponding alltitude.

ar ( ||gm ) = base * height

ar ( Δ ) = 1/2 * base * height

The parallelogram has equal sides and angles

So every angle of it is right angled

The sum of all the angles is 360 degree
