Question

Plot and connect the points A(-7,-5), B(-2,-5), C(-2,-1), D(-7,-1), and find the area of figure ABCD. A. 10 square units

B. 20 square units
C. 16 square units
D. 12 square units

Answer 1

B. 20 square units

Explanation:

You want a graph and the area of figure ABCD with points A(-7,-5), B(-2,-5), C(-2,-1), D(-7,-1).

Graph

The attachment shows a graph of the points and the rectangle they define. The side lengths of the rectangle can be found from the coordinates, or by counting grid squares.

The rectangle is 5 units wide and 4 units high.

Area

The area is the product of length and width:

A = LW = (5 units)(4 units) = 20 units²

The area of ABCD is 20 square units.
