Question

the base of the parallelogram is thrice its height if its area is 768 cm find the base and height of its of this

Answer 1

Let the height be x cm
Then
Base = 3x cm
Area of ||gm = base x height = 768cm

$3x \times x = 768 \\ 3 {x}^{2} = 768 \\ {x}^{2} = 256 \\ x = 16cm$
So,
Height = 16cm
Base = 3x16 =48cm
