Find the area of rectangle b c e f

Area is 16

Step-by-step explanation:

To obtain the area of the shown rectangle we need to obtain the dimensions of its sides.

Since all we have are coordinates, we need to apply the equation for distance between points.

That is

To obtain BF.

(x2,y2)=(0,3)

(x1,y1)=(-2,1)

BF=SQRT(4+4)=SQRT(8)=2 sqrt(2)

To obtain BC

(x2,y2)=(4,-1)

(x1,y1)=(0,3)

BC=SQRT(16+16)=SQRT(32)=4 SQRT(2)

The area of the rectangle B C E F is the product BC*BF= (2*sqrt(2) * 4*sqrt(2))=(8*sqrt(2)*sqrt(2))=8*2=16

y -5 = (-1/4)(x + 8)
