Answer:

The cost of 10 cm and 70 cm are £0.55 and £3.85 respectively.

Explanation:

Material for a dress costs £5.50 per meter.

We know that, 1 meter = 100 cm.

Suppose, the cost of 10 cm material is
x and the cost of 70 cm material is
y

Now, according to the ratio of "cost" to the "length of material" , we will get.......


(x)/(10) =(5.50)/(100)\\ \\ 100x=10*5.50=55\\ \\ x=(55)/(100)=0.55

and


(y)/(70) =(5.50)/(100)\\ \\ 100y=70*5.50=385\\ \\ x=(385)/(100)=3.85

So, the cost of 10 cm material is £0.55 and the cost of 70 cm material is £3.85
