Answer:
Read below.
Step-by-step explanation:
A=l*w
320=l*(4/5)l
320=(4/5)(l2)
(5/4)(320)=(5/4)(4/5)(l2)
5(80)=l2 (320/4=80)
400=l2
√400=√l2
20=l
w=(4/5)(20)
w=4*4 (20/5=4)
w=16
length=20 feet
width=16 feet
If you don't understand square roots, maybe you understand prime factorization.
320=2*2*2*2*2*2*5=(2*2*2*2)*(2*2*5)=16*20 and 16 is 4/5 of 20
If you don't understand prime factorization you can use trial and error.
2*160
4*80
5*64
8*40
10*32
16*20 answer, because 16 is 4/5 or 0.8 times 20
