Answer:

A

Step-by-step explanation:

Assuming you require the distance between the 2 points.

To calculate the distance d use the distance formula

d = \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2    }

with (x₁, y₁ ) = (- 3, - 8) and (x₂, y₂ ) = (- 2, - 3)

d = \sqrt{(-2+3)^2+(-3+8)^2}

   = \sqrt{1^2+5^2}

   = \sqrt{1+25}

   = \sqrt{26} → A

144=(x+7)^2  take the square root of both sides...

12=x+7  subtract 7 from both sides...

x=5

So the original was a 5m square.

...

255=WL and you are told that W=L+2 so the equation becomes:

255=(L+2)L

255=L^2+2L

L^2+2L-255=0

L^2+17L-15L-255=0

L(L+17)-15(L+17)=0

(L-15)(L+17)=0  Since L>0...

L=15yd, and since W=L+2, W=17yd so

length=15, width=17yd
