Area of square = x^2 +14x +49
Side^2 = x^2 + 2 * 7*x + (7)^2
Side^2 = (x+7)^2
Side of square = x+7 cm
Perimeter = 4* Side
= 4* (x+7)
= 4x + 28 cm
Side^2 = x^2 + 2 * 7*x + (7)^2
Side^2 = (x+7)^2
Side of square = x+7 cm
Perimeter = 4* Side
= 4* (x+7)
= 4x + 28 cm

area = x^2+14x+49
x^2 +7x+7x+49
x (x+7)+7(x+7)
(x+7)(x+7)
area= (x+7)^2
area of square = s^2
s^2 = (x+7)^2
s =x+7
perimeter of square = 4× side
=4×(x+7)
4x+21

x^2 +7x+7x+49
x (x+7)+7(x+7)
(x+7)(x+7)
area= (x+7)^2
area of square = s^2
s^2 = (x+7)^2
s =x+7
perimeter of square = 4× side
=4×(x+7)
4x+21
