A triangle has a base of 5 cm and an area of 15 cm. What is the height of the triangle?
Tap to reveal answer
The area of a triangle is (1/2)*base*height. We know that the area = 15 cm, and the base is 5 cm, so:
15 = 1/2 * 5 * height
3 = 1/2 * height
6 = height

The sum of the lengths of the shortest sides of a triangle cannot be less than the third side.
3 + 5 = 8 < 9, so 3 can't be a value of x.
