Answer:
width=5.5
Length=12
Step-by-step explanation:
L = 1+2W [eq2; “length of the rectangle is 1 yd more than twice the width”]
(1+2W)(W)=66 [substitute eq2 for L in eq1]
W + 2W2= 66 [distribute]
2W2+ W – 66 = 0 [put all term on left side]
(2W-11)(W+6) = 0 [factor or use Quadratic Formula]
Substitute for W in either formula:
L = 1 + 2(5.5)
(i don't know if you understand this)
