You have 80 pieces of fabric to make a wall hanging. each piece of fabric is a square with a side length of 5 inches. you use as many pieces of fabric as possible to create a square wall hanging. what is the area of the wall hanging? how many pieces of fabric are left over? how many more pieces of fabric would you need to increase the size of the wall hanging?

the area of a triangle is determined by the formula: base x height * 1/2

you'll need to assign a base to the triangle. based on the vertices given, the simplest base would be the line segment from (-2,1) to (2,1). the distance between any two numbers is found by just subtracting them. here, you should subtract the x values to find the distance of this side.

2 - (-2) = 4.

so the distance (aka the length of the base) is 4. the height of the triangle is the distance between the base and the highest point on the triangle which is (3,4). we should subtract the y values this time to find the height/distance.

4 - 1 = 3

so the height is 3.

base = 4

height = 3

hope this if needed hmu
