Question

Plot the points A( 3 , 3 ) and B ( -3 , 3 ) in the Cartesian plane. Join AB , OA and OB. Name the figure obtained and find its area and perimeter.

Answer 1

Step-by-step explanation:

A(3,3) and B(-3,3) and O(0,0)

The distance formula is sqrt[(x2-x1)²+(y2-y1)²]

So distances of AB is 6 units that of OA and OB are 3root(2)

Perimeter is 6sqrt(2)+6

Area is 9 square units.
