The area of a right angled triangle is 40 sq cm. If its base is equal to 28 cm. find its height.

1. 3⁶/₇ cm
2. 4⁶/₇ cm
3. 2⁶/₇ cm
4. 5⁶/₇ cm
5. None of the above

Correct Option: C

Given that,
area = 40 sq cm,
base = 28 cm and
height = perpendicular = ?

Area = (base x perpendicular) / 2
⇒ 40 = (28 x perpendicular) / 2
∴ perpendicular = 40/14 = 20/7
= 2⁶/₇ cm
