Step 1: Define

Point (7, -5)

Point (-1, -3)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m.

Substitute [SF]: $m=\frac{-3+5}{-1-7}$
Add/Subtract: $m=\frac{2}{-8}$
Simplify: $m=\frac{-1}{4}$

What is the area of this figure?

coldgirl [10]

Answer: 102

-----------------------------------------------

We'll use the formula
A = h*(b1+b2)/2
where
A = area of trapezoid
h = height
b1 & b2 are the parallel bases

In this case,
b1 = 6+7 = 13
b2 = 21
h = 6

Making the area to be
A = h*(b1+b2)/2
A = 6*(13+21)/2
A = 6*(34)/2
A = 204/2
A = 102

Side Note: We don't use the slanted side of 10 cm at all
