Question

The cost of making a fence is directly
proportional to the length of the fence. The
cost for a 4 m fence is 240.
(a) Find the cost for a 7 m fence.
(b) If Yusuf has a budget of only 350, what
is the maximum length of fence he can
make?​

Answer 1

Answer:

(a) cost of making 4m fence=240

coast of making 1m fence=240/4=60

therefore cost of making 7m fence=60*7=420

(b) length of fence in 240rs.=4m

length of fence in 1rs.=4/240m=1/60m

length of fence in 350rs.=(1/60)*350rs.=35/6m=5 5/6m

Answer 2

★ a) 420 rupees

★ b) 5 meter fence

a) Find the cost for a 7 m fence.

Given that:-

The cost for a 4 m fence is 240.

Solution:-

=>The cost for a 4 m fence is 240.

=>The cost for a 1 m fence

$= > \frac{240}{4}$

$= > 60$

$= > The \: cost \: for \: a \: 7 \: meters \: fence =60 \times 7$

$= > 420$

•°•The cost for a 7 meters fence = 420

b) If Yusuf has a budget of only 350, what

is the maximum length of fence he can

mmae

Given that:-

The cost for a 4 m fence is 240.

Solution:-

=>The cost for a 4 m fence is 240.

=>The cost for a 1 m fence

$= > \frac{240}{4}$

$= > 60$

If Yusuf has buhget of 350 then = 350÷60

$= > \frac{350}{60}$

•°•If Yusuf has buhget of 350 then he can make = 5 meter fence
