gayaneshka [121]

Answer:

Step-by-step explanation:

Since it is a rectangle, we know that there are two pairs of sides the same length. All we have to do is add each number by itself, and add those numbers together, or you can envision it like this graph I made.

1) $400 interest is earned on a principal of $2,000 at a simple interest rate of 5%
Kitty [74]

Answer:

4 years

Step-by-step explanation:

I = $ 400

R = 5%

P =$ 2000

I = Prt

400 = 2000 * \frac{5}{100} * t

400 = 20 * 5 * t

400 = 100 t

\frac{400}{100}=t

t = 4 years

A carpenter has a rectangular wooden board. The diagonal of the board is 18 inches long and one side of the board is 12 inches l
BaLLatris [955]

In this question, it is given that the diagonal of the board is 18 inches long and one side of the board is 12 inches long.

Let the other side is of length b inches .

Now we use pythagorean identity, which is

a^2 + b ^2 = c^2

Here, a = 12 and c=18

Substituting these values, we will get

12^2 + b^2 = 18^2 \\ 144 + b ^2 = 324 \\ b^2 = 324-144 \\ b^2 = 180 \\ b= \sqrt{180} \\ b = 13.4164 inches

And the formula of perimeter is

Perimeter = 2(Sum\ of \ legs)

Substituting the values of the two legs, we will get

Perimeter = 2(12+13.4164) = 50.83 inches
