Question 74

The base of the parallelogram is twice of its height and its area is $$288 cm^2$$. The base of the parallelogram is:

Solution

Let height of parallelogram = $$x$$ cm and base = $$2x$$ cm

=> Area = base $$\times$$ height

=> $$x\times2x=288$$

=> $$x^2=\frac{288}{2}=144$$

=> $$x=\sqrt{144}=12$$

$$\therefore$$ Base = $$2\times12=24$$ cm

=> Ans - (B)
