The area of a right-angled triangle is 96 sq metres. If the base is three times the altitude, find the base.

Text Solution

Verified by Experts

The correct Answer is:
24 m
Let the altitude be x metres. Then, base = 3x metres.
`:." "(1)/(2)xx3x xx x=96impliesx^(2)=64impliesx=8m. Hence, base = 24 m.
