I have three linear equations & they form a triangle, how do i find the triangles area?

I also have the intercept points.
I have to use the information above (equations and intercepts) to find the area.
Help please!
The equations are y=2x+2, y= -x+5 and y=1/2x-1
the intercepts are (1,4) (-2,-2) and (4,1)
First take the distance between each intercept:
d = sqrt((second x – first x) ^2 + (second y – first y)^2)
So the distance between [...]

why does the geometric formula for the area of a regular polygon work?

so, i know that it’s the apothem/2 , times the perimeter of th figure.
why does this formula work in finding the area?
In a regular polygon, the apothem is perpendicular to each of the sides. Therefore you could divide the polygon into n separate triangles, with the center of the polygon as one point and each [...]

Should have said "cornice". Don’t want to have to take it all down (lg room) and the damaged areas are only about 2-3 inches long.
I have remodled several old houses with cornice work.

Why can’t you used the rhombus area formula to find the area of a square?

Why are the area formula for a square and the area formula for a rhombus only equal when the angles are all 90 degrees?
You seem to be labouring under a serious misapprehension. Of course you can use the rhombus formula for a square. There are several formulae which are used for the rhombus [...]
