Answer:

a) Perimeter  = 10.25 cm

b) Area = 5 cm²

Step-by-step explanation:

a) Perimeter

To find the perimeter we need to add the measure of the three sides of the triangle

P = 2.75 cm + 3.5 cm + 4 cm = 10.25 cm

b) Area

To find the area we need the length of the height and the length of the base.

base = 4 cm

height = 2.5 cm

Formula

Area = base x height /2

Area = 4 x 2.5 / 2 = 5 cm²

A 3 L bottle of oil costs $36 and contains 12 cups. Dinesh puts 1 cup of oil, 10 garlic gloves and 1 cup of
saul85 [17]

The correct answer is $15

Explanation:

The first step is to determine the total of oil that was used for the 5 batches. To find this, you just need to multiply the amount of oil used for one batch by the total batches.

1 cup of oil per batch x 5 batches = 5 cups of oil

This means, in the 5 batches the oil Dinesh used was 5 cups of oil. Additionally, you know the total of cups in the bottle of oil is 12 cups, and these 12 cups or total costs $36. Now to find what is the cost of the 5 cups use the rule of three and cross multiplication.

12 cups of oil = $36   1. Write the values

5 cups of oil  = x      

12 x = 180           2.  Cross multiply this means 36x 5 and 12 multipy by x

x = 180 ÷ 12        3. Solve the equation

x=  15 - Cost for 5 cups used in the batches
