The formula for the area of a triangle of base b and altitude h is A = (1/2)(b)(h).
Here, b = 18 cm and h = 9 cm. Thus, the desired area is:
(18 cm)(9 cm)
A = ----------------------- = 81 cm^2
2
This problem gives you more info than is needed to solve it. The area of the given triangle is 81 cm^2.
An
1/2
Step-by-step explanation:
There are 10 balls total and two balls are removed and not replaced so your fraction is 4/8 but you need to simplify it to 1/2
