Fine the area of the regular figure

139.5 mm

Step-by-step explanation:

The area of a geometric shape with all sides of equal length is:

A (1/2)nsr

n = the number of sides

s = the length of the sides

r = the length of the apothem

The apothem is the line going from the center point of the shape to the middle of one of the sides.

A = (1/2)(5)(9)(6.2)

A = (1/2)279

A = 139.5 mm

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)
