The dimensions of this bilum cloth is 12cm by 18cm.Marie wants to make a dress and she needs 150 square centimeter of cloth.How much will she pay for the cloth?

First, we need to calculate the total area of the bilum cloth:

Area = length x width
Area = 12cm x 18cm
Area = 216 square centimeters

Since Marie needs 150 square centimeters of cloth for her dress, she will only need to purchase 150 square centimeters from the bilum cloth.

The cost of the cloth will be based on the total area of the bilum cloth, so we need to calculate the cost per square centimeter:

Cost per square centimeter = Total cost of bilum cloth / Total area of bilum cloth
Cost per square centimeter = Total cost of bilum cloth / 216 square centimeters

Let's say the total cost of the bilum cloth is $X. We can now set up an equation to find the cost per square centimeter:

X / 216 = Cost per square centimeter

Now we can calculate the cost per square centimeter:

Cost per square centimeter = X / 216

Since Marie only needs 150 square centimeters of cloth, we can calculate the total cost for the cloth she needs:

Total cost = Cost per square centimeter x 150 square centimeters

Now we can substitute the values and calculate the total cost for the cloth Marie needs.

1. Calculate the area of the bilum cloth.

Area = Length x Width
Area = 12cm x 18cm
Area = 216 square centimeters

2. Determine how many bilum cloths Marie needs.

Number of cloths = Total area required / Area of one cloth
Number of cloths = 150 square centimeters / 216 square centimeters
Number of cloths = 0.6944 (rounded up to 1)

3. Calculate the total cost of the cloth.

Since Marie needs 1 bilum cloth, she will pay for that amount.

Cost of 1 bilum cloth = $0.25

Therefore, Marie will pay $0.25 for the cloth.
