r-ruslan [8.4K]

Answer:

AB=131\ ft

Step-by-step explanation:

we know that

The perimeter of the rectangular lot is

P=2(AB+BC) ----> equation A

where

AB is the length

BC is the width

we have

AB=2BC-1 ---> equation B

P=394\ ft ----> equation C

substitute equation B and equation C in equation A

394=2(2BC-1+BC)

solve for BC

394=2(3BC-1)

394=6BC-2

6BC=396

BC=66\ ft

<em>Find the value of AB</em>

AB=2BC-1

AB=2(66)-1

AB=131\ ft

Answer: 0.72/20; 1.98/20; 17.3/20

0.036 * 10/10 = 0.36/10 * 2/2 = 0.72/20

0.099 * 10/10 = 0.99/10 * 2/2 = 1.98/20

0.865 * 10/10 = 8.65/10 * 2/2 = 17.3/20
