Llana [10]

Answer:

C(-4,-2), D(3,-7)

Ar=35unit^{2}

Step-by-step explanation:

we procced to identify points:

A(-4,-7), B(3,-2)

for being the sides of a rectangle parallel to the axes, we find the other two vertices (VIEW GRAPH)

C(-4,-2), D(3,-7);  Area of the rectangle Ar=b*h, where

b=(X_{D}-X_{A}); h=(Y_{B}-Y_{D})

So Ar=(3-(-4))*(-2-(-7)) = (3+4)*(-2+7)=7*5=35unit^{2}
