This figure is made up of a triangle and a semicircle. what is the area of the figure? use 3.14 for π . enter your answer, as a decimal, in the box. units² a composite figure made up of a triangle with vertices at negative 3 comma negative 2, negative 2 comma 3, and 1 comma negative 2 and a semicircle below the triangle such that the diameter extends from negative 3 comma negative 2 to 1 comma negative 2.

Step-by-step explanation:

Plot the points mentioned on a x-y plane and then follow step by step as shown to find the area of the composite figure which contains a triangle and a semicircle attached.

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
