Name 2 strategies that you can use to find the area of a shape

Answers

1. Multiply the dimensions

2. Make two smaller shapes and multiply each dimensions then add the answers together to get the final answer

First, it depends what shape it is.

To find the area of the:

square/rectangle: L x W (length times width)\

Triangle: 1/2 x b x h (One half times base times height)

Parallelogram: b x h (base times height)

Circle: $\pi$ x r^2 (Pi times radius to the power of 2)

Trapezoid: 1/2 x (a+b) x h (One-half times Base 1 plus Base two times height

Disclaimer: These are the areas for MOST shapes, not all.

hope this helpeed :)

Which classification best represents a triangle with side lengths 6cm, 10cm, and 12 cm?

Answers

We can sort out this triangle as a scalene triangle, that is, a triangle that has three unequal sides. It is also true that there are no equal angles for this type of triangles. If a scalene triangle has an angle of 90°, then this is called a right triangle. But this is not right triangle. Let's prove it:

We know that the Pythagorean Theorem establishes that:

$c^2=a^2+b^2 \n where \ a \ and \ b \ are \ the \ sides \ and \n c \ is \ the \ Hypotenuse \ that \ is \ always \ the \ greatest \ side$

Therefore, we can say that:

$a=10cm \n b=6cm \n c=12cm$

Accordingly:

$12^2 \neq 10^2+6^2 \therefore \boxed{144 \neq 136}$

In fact, this is not a right triangle.

a middle school has 490 students and mae surveys a random sample of 60 students and finds that 24 of them have pet dogs how many are likely to have pet dogs

Answers

If you would like to know how many students are likely to have pet dogs, you can calculate this using the following steps:

24 students have pet dogs ... 60 students
x students have pet dogs = ? ... 490 students

24 * 490 = 60 * x /60
x = 24 * 490 / 60
x = 196 students

Result: 196 students are likely to have pet dogs.
