Question

5. If you plot the points (0, 0), (2,0),(2,2)and (0,2) and join them in
order, name the quadrilateral so obtained, based on your
observations and find its area.​

Answer 1

Use distance formula

Let denote pt.(0,0) by A and similarly other by B,C and D respectively

AB=√(x2-x1)²+(y2-y1)²=√(2-0)²+(0-0)=√2²+(-0)=2

Similarly by Using distance formula BC=2

CD=2

AD=2

AC=4

BD=4√2

Because all sides are equal but diagnols are not equal therefore it is a rhombus
