The height of the triangle is 60cm, or 20cm+ 40cm.

The equation for area of a triangle is A=1/2bh

Your base is 30 cm height is 20cm.

A=1/2(30)(20)
A=1/2(600)
A=300cm^2

Your answer is 300cm^2

Answer:

[tex]height = (20 + 40) cm\\ = 60cm \\ area = \frac{1}{2} \times b \times h \\ = \frac{1}{2 } \times30 \times 60 \\ = \frac{1800}{2} \\ area= 900 {cm}^{2} [/tex]
