Find the area of the triangle (5.4cm) base

(2cm) height

dotted lines to make it a right triangle

One of the many ways to solve the area of a triangle is to divided by two the product of its base (b) and height (h). Which can be expressed as,

A = (b x h) / 2

Substituting the given base and height to the equation,

A = (5.4 cm x 2 cm) / 2 = 5.4 cm^2

Therefore, the area of the triangle is 5.4 cm^2.
