Question

rectangle PQRS has its coordinate at P(-8,2),Q(-5,6),R(3,0) and S(0,-4)

a.)Find its Area
b.)Find its Perimeter

Answer 1

steps to answer this question :
draw the rectangle PQRS on a Cartesian plane (follow coordinate given)
find distance by using formula \[d = \sqrt{(X2-X1)^2 + (Y2-Y1)^2}\]
then you have length of all sides..
use formula length x length to find area..
sum of all sides is calculate to find perimeter..
