Question

the area of as square is numerically equal to twice its perimeter .find the lenght of a side of a square
with solution plss

Answer 1

let the side of the square be a. Area of the square=a^2 . Perimeter of the square =4(a)=4a. it is given a^2-8a=0=> a(a-8)=0=> a=0 or a=8 So a=8. length of the side of the square is 8.

Answer 2

Heya !!





Let side of square be X unit.




Area of square = (Side) ² = X² unit²



And,




Perimeter of square = 4 × Side = 4X unit.





According to the question,





Area of square = 2 ( Perimeter of square )





X² = 2 ( 4X )




X² = 8X





X² - 8X = 0




X (X - 8 ) = 0





X = 8 unit.



Side of square = X = 8 units.
