The area of a rectangle is given by length times width. Therefore, the area of the given rectangle is:

Area = length x width = 32 x 20 = 640 square inches.

So the answer is 640 in. 2

a. To find the outside dimensions of the area surrounding the pool, we need to add 15 feet to each side of the pool.

Length with the fence = 22 + 2(15) = 52 feet
Width with the fence = 23 + 2(15) = 53 feet

Therefore, the outside dimensions of the area surrounding the pool are 52 feet by 53 feet.

b. To calculate the amount of fencing needed, we need to find the perimeter of the area surrounding the pool.

Perimeter = 2(length + width)
Perimeter = 2(52 + 53)
Perimeter = 2(105)
Perimeter = 210 feet

Therefore, John will need 210 feet of fencing.

So the answer is 52 ft by 53 ft; 210.

To find the area of a triangle, we use the formula:

Area = 1/2 x base x height

In this case, the base is the length of 82 and the height is the length of 26.

Area = 1/2 x 82 x 26
Area = 1,066 square feet

Therefore, the area of the given triangle is 1,066 ft.

The area of a parallelogram is given by the product of its base and height. Therefore, the area of the given parallelogram is:

Area = base x height = 276.5 cm x 20.3 cm = 5,612.95 cm²

So the answer is 5,612.95 cm².

The formula for the circumference of a circle is:

Circumference = 2 x π x radius

where π (pi) is approximately 3.14.

The radius of the given circle is 17cm, so we can substitute this value in the formula:

Circumference = 2 x π x 17
Circumference = 2 x 3.14 x 17
Circumference = 107.08 cm

Rounding to the nearest unit, the circumference of the circle using 17cm as the radius is approximately 107 cm.

So the answer is 107 cm.

The circumference of a circle is related to its diameter by the formula:

Circumference = π x diameter

We are given the circumference of Earth at the equator as 40,074 kilometers, so we can use this formula to find the diameter:

π x diameter = 40,074
diameter = 40,074 / π
diameter ≈ 12,756 kilometers (rounded to the nearest kilometer)

Therefore, the diameter of Earth to the nearest kilometer is approximately 12,756 kilometers.

So the answer is 12,762 km.
