A rectangular plot of ground is 5 meters longer than it is wide. It's area is 20,000 square meters. What is the deminsion
Reil [10]
The formula for area is A = bh
B = Length
H = Width

If B is 5 times longer than H...

A = 5x(x)

Now let's solve

20000 = 5(x)(x)
20000 = 5x^2
   /5          /5
  4000 = x^2
    *square*
      20 = x

The height (width) is 20. (x)
The base (length) is 100 (5x -> 5(20) -> 100)

Proof: 20 times 100 = 20000

This Is One Answer, There Are More Then One Answer.



100 / 5 = 20 + 27 = 47 / 2 = 23.5

100 = my number
5 = divide by

100 / 5 = 20
27 = add
20 = results of last answer
Then 20 + 27 = 47
47 = results of last answer
2 = half of
Then 47 / 2 = 23.5

Order the numbers from least to greatest. 0.3, 9/25, 33%, 0.35
Finger [1]

Answer:

0.3(least)

0.33

0.35

0.36(greatest)

Step-by-step explanation:

Okay, so first we need to have all of our numbers in the same category of variable. So first, we will convert 9/25 to a decimal.

To do that, we must divide 9 by 25 to get our answer of 0.36.

Now, we will convert the 33% to a decimal by dividing it by 100 to get 0.33

We now have our list, which should be ordered as:

0.3

0.33

0.35

0.36
