Area = length * width

65 meters

65 meter

need the quadratic equation here

X

factor

(X + 13)(X - 5)

------as you see

X = - 13

------discard

X = 5

------keep as the width

X + 8 = 13

------so

Width = 5 meters

======

length = 13 meters

======

65 meters

^{2}= X * (X + 8 m)65 meter

^{2}= X^{2}+ 8Xneed the quadratic equation here

X

^{2}+ 8X - 65 = 0factor

(X + 13)(X - 5)

------as you see

X = - 13

------discard

X = 5

------keep as the width

X + 8 = 13

------so

Width = 5 meters

======

length = 13 meters
