A couple wanted to install a square mirror that has:
Area of the mirror = 500 square inches.
x = nearest tenth of an inch , length of wood needed
s = sides of square
Area = s2
500 (area) = s2 | √
x = √500
=> √ 5 x 100
=> √ 5 x √100
=> 10 √ 5
=> approximately 22.4
Since we’re looking for the nearest tenth of decimal place value, the answer is approximately 22.4

First you need to convert the mixed numerals to improper fractions , for example 1 1/3 = 1/3 + 3/3 = 4/3. Then you multiple across the numerators, the top number, and then the denominator, the bottom number. Simplify the answer if necessary.
1 1/3 x 5/6
4/3 x 5/6 = 20/18 Divide numerator and denominator by 2
10/9 write as a mixed number 1 1/9
