What is the area of the rectangle shown on the coordinate plane?

The area of rectangle is 42 square unit.

Step-by-step explanation:

We are given a rectangle shown in diagram.

We need to find the area of rectangle.

First we have to find the L and B of the rectangle.

Using coordinate system find the coordinate of vertex of rectangle.

Using distance formula to find the distance of leg of rectangle.

A(2,-1)     B(9,-8)     C(12,-5)  

Distance formula:

Hence, The area of rectangle is 42 square unit.

i think it's b

step-by-step explanation:

because the graph is 2 above (0,0)
