Determine the area of the triangular ABC with AC=5cm and height DB=30 mm.<br>

Lady_Fox [76]

Answer:

750 mm²

Step-by-step explanation:

<h3>Area of triangle:</h3>

To find the area of the triangle, multiply the base and height and then divide the result by 2.

$\sf \boxed{\bf Area \ of \ triangle = \dfrac{1}{2}*base *height}$

base = AC = 5 cm = 50 mm

height = DB = 30 mm

$\sf = \dfrac{1}{2}*50*30\\\\= 25 *30\\\\= 750 \mm^2$
