The formula of an area of a triangle:

A_\Delta=\dfrac{base\cdot height}{2}

We have:

base = 10 cm and height = 20 cm. Substitute:

A_\Delta=\dfrac{10cm\cdot20cm}{2}=\dfrac{200}{2}\ cm^2=100\ cm^2

<h3>Answer: 100 cm²</h3>

Area of a triangle = 1/2 base * height

A = 1/2 (10)* 20

A= 5*20

A = 100 cm^2
