If a triangle has a base of 5 cm and a height of 6 cm,
what is its area?

15cm^2

Step-by-step explanation:

The formula for solving the area of a triangle is 1/2base×height

Base=5cm

Height=6cm

So let's apply the formula

1/2×5×6

6×5/2

30/2

15cm^2

Therefore the area of the triangle is 15cm^2
