Question

The base of parallolegram is twice it's height. If it's area is 800cm, find it's height and base. (Hint -take height=x, base=2x, area=2x×x=800)

Answer 1

Answer:

Step-by-step explanation:

HEIGHT = x

BASE = 2x

AREA = BASE × HEIGHT

800 = 2x × x

800 = 2x^2

x^2 = 800/2

x^2 = 400

x=√400

x = 20 cm

Therefore,

Height = x = 20 cm

Base = 2x = 2×20 = 40 cm
