Tomtit [17]

From home to Supermarket = 1 3/4 + 1/4
= 7/4 + 1/4 = 8/4 = 2 miles

Back journey = 2 + 2 1/5 = 2 + 11/5 = 21/5

So, total distance = 2 + 21/5 = 31/5

<h2>Minimum cost is 1800 $</h2>

Step-by-step explanation:

Let l be the length of west side and w be the length of north side.

East side = West side = l

North side = South side = w

Area = lw = 540 ft²

We have

$lw=540\\\\w=\frac{540}{l}$

Cost for fencing

C = 30 w + 30 l + 20 w = 30 l + 50 w

$C=30l+50\times \frac{540}{l}\\\\C=30l+\frac{27000}{l}$

At minimum cost derivative is zero,

That is

$dC=30dl-\frac{27000}{l^2}dl\\\\30-\frac{27000}{l^2}=0\\\\30=\frac{27000}{l^2}\\\\l^2=900\\\\l=30ft$

We have

lw = 540

30 x w =540

w = 18 ft

Cost = 30 l + 50 w =30 x 30 + 50 x 18 = 1800 $

Minimum cost is 1800 $
