Answer 1

Answer:-

• Side of square= 8

Given:-

• Area of square is equal to twice its perimeter

To find:-

• Side of square= ....?

Solution:-

Let the side of square be a

Perimeter of square=4a

$area \: of \: square = {a}^{2}$

Now ATQ,

$area \: of \: square = 2 \times \: perimeter \: of \: square$

${a}^{2} = 2 \times 4a \\ {a}^{2} = 8a \\ a = 8$

Hope its help uh❤

Answer 2

Answer:

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.
