If a number is multiplied by the same number, the result is a square. The inverse of the square is a square root. The square root is used in various fields such as vehicle design, finance, etc. Here, we will discuss the square root of 49/144.
The square root is the inverse of the square of the number.
The fraction 49/144 is a perfect square, as both the numerator and denominator are perfect squares.
The square root of 49/144 is expressed in both radical and exponential form.
In the radical form, it is expressed as √(49/144), whereas (49/144)(1/2) in exponential form. √(49/144) = 7/12, which is a rational number because it can be expressed in the form of p/q, where p and q are integers and q ≠ 0.
The prime factorization method can be used for perfect square numbers.
For fractions that are perfect squares, we can find the square root of both the numerator and the denominator separately.
Let us now learn the following methods:
The product of prime factors is the prime factorization of a number.
Now, let us look at how 49 and 144 are broken down into their prime factors:
Step 1: Finding the prime factors of 49 and 144. - 49 = 7 x 7 = 7² - 144 = 2 x 2 x 2 x 2 x 3 x 3 = 2โด x 3²
Step 2: Since both 49 and 144 are perfect squares, we can directly find the square roots: - √49 = 7 - √144 = 12
Therefore, √(49/144) = 7/12.


The simplification method is a straightforward approach to finding the square roots of fractions.
Let us learn how to find the square root of 49/144 using simplification:
Step 1: Identify the perfect squares in the numerator and the denominator. - √49 = 7 - √144 = 12
Step 2: Simplify the square root of the fraction by taking the square root of the numerator and the denominator separately: - √(49/144) = 7/12
Thus, the square root of 49/144 is 7/12.
Students often make mistakes while finding the square root of fractions, such as not simplifying the fraction first or incorrectly applying the square root separately to the numerator and denominator.
Let us look at a few common mistakes and how to avoid them.
Can you help Max find the side length of a square if its area is 49/144 square units?
The side length of the square is 7/12 units.
The area of the square = side².
The area is given as 49/144 square units.
Therefore, side = √(49/144) = 7/12.
Thus, the side length of the square is 7/12 units.
A rectangular garden has an area of 49/144 square meters. If the length is โ49 meters, what is the width of the garden?
The width of the garden is 1/12 meters.
The area of the rectangle = length × width.
Given, length = √49 = 7 meters and
area = 49/144 square meters.
Width = Area / Length
= (49/144) / 7
= 1/12 meters.
Calculate 5 ร โ(49/144).
The result is 35/12.
First, find the square root of 49/144, which is 7/12.
Then, multiply by 5:
5 × 7/12 = 35/12.
What is the square root of (49 + 95/144)?
The square root is 13/12.
First, find the sum: 49 + 95/144
= 49/1 + 95/144
= 7201/144.
Then, find the square root:
√(7201/144) = 13/12.
A square plot measures 49/144 square meters in area. What is the perimeter of the plot?
The perimeter of the plot is 28/12 meters, or 7/3 meters.
Side of the square = √(49/144) = 7/12.
Perimeter of the square = 4 × side
= 4 × 7/12
= 28/12 meters or 7/3 meters.
