Question

The area of a right triangle is 180 c m 2 . Find the height if the base of the triangle is 20 cm.

Answer 1

Answer:

area = 1\2×base × height

180 = 1/2 ×20× h

360 = 20h

18 = h

Answer 2

$area = 180 {cm}^{2}$

$area \: of \: triangle = \frac{1}{2} \times base \times height$

$180 = \frac{1}{2} \times 20 \times h$

$18 = h$

thus, height of the triangle is 18cm
