What is the formula for the area of a square? If you know the area of a square, how can you find its side length? Write the side length of each square as a square root.
Is each side length rational or irrational? Explain.

Area of the square = 121 sq. m , So length of the each are = √[121] = 11 m. , So, the perimeter of the square=4*11 mtr. = 44 mtr.

Step-by-step explanation:

s=+√A

Step-by-step explanation:

The area of a square is A=s² where A is the area of a square with a side length of s units. Therefore, the side length of a square given its area is s=+√A

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%
