Question

Please help and show work!! :)

Answer 1

base of the triangle ie PQ=2+2=4units     (only magnitude)

we know that area of triangle=1/2*base*height

4=1/2*4*height

height=2 units

ie 2 units from the mid point of PQ cause the height(altitude) is always perpendicular to  the base of the triangle

x coordinate=0 cause it lies on y axis

y coordinate=1-2=-1

(0,-1)
