What is the triangle's height in metres? I. The triangle's area is 20 times its base. II. The triangle's circumference is equal to the perimeter of a square with a side of 10 cm.
A. I alone sufficient while II alone not sufficient to answer B. II alone sufficient while I alone not sufficient to answer C. Either I or II alone sufficient to answer D. Both I and II are not sufficient to answer
Explanation: I. A = 20 x B 1/2x B x H = 20 x B H = 40; II. A = 20 x B 1/2x B x H = 20 x B H = 40; III. A = 20 x B 1/2x B x H =I am the only one who can provide an answer.According to II, the triangle's circumference is 40 cm.This does not reveal the triangle's height.
