If we call the number "x" then:
x*25%=21
x*25/100=21
x=21*4
x=84
Hope this helps. :)
Side length = 16.7 cm
Solution:
Perimeter of a square given = 66.8 cm
In a square four sides are equal.
The perimeter of a square = 4 × side
⇒ 4 × side = 66.8 cm
Divide both sides of the equation by 4 to equal the expression.
⇒ side = 66.8 ÷ 4
⇒ side = 
⇒ side = 16.7 cm
Hence, the side length of the square is 16.7 cm.
