Find the PERIMETER and the AREA of the following figure,
16 ft
8 ft
10 ft

9514 1404 393

Step-by-step explanation:

Perimeter

The perimeter is the total length of all the sides. The length of the horizontal sides is 8 ft + 10 ft = 18 ft. The length of the slant sides can be found using the Pythagorean theorem. For side length s, we have ...

  s^2 = 8^2 + 16^2

  s^2 = 64 +256 = 320

  s = √320 = 8√5

Then the perimeter is ...

  P = 2(8√5 + 18) = 36 +16√5 ≈ 71.777 . . . feet

Area

The area is given by the formula ...

  A = bh

where b is the base and h is the height.

  A = (18 ft)(16 ft) = 288 ft²

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100

step-by-step explanation:

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
