Answer:

45 cm^2

Step-by-step explanation:

The area of a triangle can be found using:

a= (b*h)/2

We know the base is 18 cm and the height is 5 cm. Therefore, we can substitute 18 in for b, and 5 in for h.

a=(18*5)/2

Multiply 18 and 5 first

a=90/2

Divide 90 by 2

a=45

So, the area is 45 cm^2

Answer:

45 cm

Step-by-step explanation:

Finding the area of a right triangle is like finding the area of a rectangle, only half. You multiply the base by the height, which would be 90 cm in this case, then divide this by half. So, the area would be 45 cm^2.
