the area of a parallelogram is 72 cm ^ 2 and its altitude is twice the corresponding base. what is the length of the base?
sqrt(divide(72, const_2))
let base = x cm height = 2 x cm area = x ã — 2 x = 2 x ^ 2 area = x ã — 2 x = 2 x ^ 2 area is given as 72 cm ^ 2 2 x ^ 2 = 72 x ^ 2 = 36 x = 6 cm answer : c
