Find the area of the triangle SHOW WORK

The area of triangle is 1263.6 mm².

This is an Equilateral triangle.

Step-by-step explanation:

Given that the area of triangle formula is A = 1/2×base×height. So you have to substitute the values into the formula :

Let base = 54mm,

Let height = 46.8mm,

This is the Equilateral triangle because all sides of the triangle are equal.

1/800 is the right answer

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
