A rectangular field has dimension of 91 feet by 60 and 1/3 feet what is the area of the field

Oliga [24]

Answer:

Area = $91*\frac{181}{3}=5490\frac{1}{3}$ square feet

Step-by-step explanation:

The area of a rectangle is given by the formula:

A = length * width

Where length is 91 feet and width is $60\frac{1}{3}$ feet

Before we do the multiplication, we have to change the mixed number [width] into an improper fraction by using the rule shown below:

$a\frac{b}{c}=\frac{(a*c)+b}{c}$

Hence,

$60\frac{1}{3}=\frac{181}{3}$

So, the area is:

Area = $91*\frac{181}{3}=5490\frac{1}{3}$ square feet

Find the square root of 6400 by using prime factorization method

Troyanec [42]

6400 = 2*2*2*2*2*2*2*2*5*5 = 2^8 * 5^2

Square root of 2^8 = 2^4 and square root of 5^2 = 5

So the answer is 2^4 * 5

= 16 * 5

= 80
