Am I finding the area of this wierd shape correctly if not what am I doing wrong?

saw5 [17]

Answer:

8 $ft^2$

Step-by-step explanation:

Sadly, you are doing this incorrectly.

The easiest way to find the area of this shape is to separate it into a square and a triangle.

This will leave you with a square with the dimentions 2x2 a triangle with a base of 4 and a height of 2.

The area of the square is 4 $ft^2$

Using the equation for the area of a triangle

$A=\frac{1}{2} bh$

We can plug in our 2 know values to get

$A=\frac{1}{2} (4)(2)\\A=4$

Now we can take the sum of the areas of these two shapes to get a total area of 8 $ft^2$

2. A circular patio has a diameter of 18 feet. How

lisabon 2012 [21]

Answer: So to cover the patio it would take 255 whole tiles. 254.469 if you want to be exact.

Step-by-step explanation:

When finding flooring needed we are finding for area. We know the formula for finding the area of a circle is A= $\pi r^{2}$ so we plug in our known variables...

we know r because radius is half of diameter and diameter was given in problem. So half of 18 is 9.

r=9

A= $\pi 9^{2}$

A= $\pi$ 81

A=254.469
