Answer 1

Answer:

Area = 8 sq units

Step-by-step explanation:

Given vertices:

(1, 1),(1, 3),(5, 3),(5, 1)

To figure out area graph the vertices and count how many units are inside.

8 sq units

So 8 sq units is the area.

Area = 8 sq units

Answer 2

d=√((x2-x1)²+(y2-y1)²)

Using above formula,

AB= 2

BC = 4

CD = 2

AB= 4

A = l×b = 2×4 = 8 sq unit
