What is the area of this triangle?

99 cm^2

Step-by-step explanation:

Since the area of a triangle is simply base x height / 2, we can just plug in the numbers.

18 x 11 = 198

198/2 = 99

Thus, our area is 99 cm^2

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get
