Answer:
45 cm
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.
45 cm^2
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
