Please help me thanks

Answer:

117.53 feet^2

Step-by-step explanation:

So to start off we need to find the area of the pentagon.

The formula for the area of a pentagon is weird so I’m not going to write it but you can search it up.

So the area would be 27.53 inches^2.

Now for the triangles.

There is 5 triangles in total with a base of 4 and a height of 9.

So the area of one is base*height divided by two.

So it would be 18.

Now we can just multiply 18 by 5 which is 90 feet^2.

So when we add up 90 and 27.53 we get 117.53 feet^2.

Aleksandr-060686 [28]

Answer:

Mauricio needs 10.5 liters of oil for frying.

Step-by-step explanation:

It is given that,

Mauricio can fry 6 potatoes using 1 liter of oil.

So, he can fry 18 potatoes using $\frac{1}{6}\times 18$ = 3 liters of oil.

Thus, Mauricio fries 18 potatoes using 3 liters of oil per hour

Now, Mauricio wants to fry the 18 potatoes for 3.5 hours.

So, the total amount of oil needed by him = 3.5 × 3 = 10.5 liters.

Hence, Mauricio needs 10.5 liters of oil for frying.
