Answer:

48.6

Step-by-step explanation:

Given:

- The triangle base is 18.

- The triangle height is 5.4.

Find the area of the triangle.

Area of triangle = (base · height) / 2

We take

(18 · 5.4) / 2 = 48.6

So, the area of the triangle with a base of 18 and a height of 5.4 is 48.6 square units.

area of triangle is 1/2multiplide by base multiple height 1/2 multiple 18 multiple 5.4 answer is 48.6
