Find the area of a square if the perimeter is equal to 38 in.
Misha Larkins [42]
Hello! I would love to help!

Alright! We know that perimeter is basically adding all the sides of a shape together. We also know that a square has 4 sides, so 38 is the result of 4 sides being added. Now, we also know that all sides of a square are even. So, to find one side of a square, we just need to do 38/4


38/4=9.5


Alright. So now we know one side of a square is 9.5 in. We know that in order to find area, we have to multiply length and width. We know that since all sides of a square are even, 9.5 is both our length and width. So, in order to find the area, we just have to multiply 9.5 by 9.5

9.5*9.5=90.25

Alright! So we have determined your answer!!!


90.25 or in fraction form 90 1/4 inches squared!

Hope this helped! Comment if you have questions!!

Using 7 1/2 / 3/4 = 60/6=10 interpret the meaning of the quotient in terms of the two fractions given
maks197457 [2]

Answer:

Here's what I get.

Step-by-step explanation:

x = 7\frac{1}{2} \div \frac{3}{4}

1. Convert the mixed number to an improper fraction

x = \dfrac{15}{2} \div \dfrac{3}{4}

2. Invert the proper fraction and change division to multiplication

x = \dfrac{15}{2} \times \dfrac{4}{3}

3. Multiply numerators and denominators

x = \dfrac{60}{6}

4. Divide the numerator and the denominator

x = 10

The quotient is what you get after you invert the denominator in Step 2 and then multiply the two fractions in Step 3.
