Hmmm. 20 or 30 so the teacher will count the rest,if a student guessed, wrong or right
Answer:
13 yds * 32 yds
Step-by-step explanation:
A=area, l=length, w=width
A=w*l
l=6+2w
A=w*(6+2w)
A=6w+2w^2
416=6w+2w^2
416/2=(6w+2w^2)/2
208=3w+w^2
208-208=3w+w^2-208
w^2+3w-208=0
w^2+16w-13w-208=0
w(w+16)-13(w+16)=0
(w-13)(w+16)=0 ==> w+16=0 ==> w=-16, w can't be negative.
w-13=0
<u>w=13</u>
l=6+2w
l=6+2(13)
l=6+26
<u>l=32</u>
Dimensions: 13 * 32
