Question

what happens to the area of a sq. if its side is doubled​

Answer 1

Answer:

side^2 = area of square

(2a)^2 = 4 a^2

it becomes 4 times

Answer 2

let side of square be L

so, initial area of square, A = L^2

now length is double means become 2l

so, area now is equal to, Á = 2L × 2L = 4L^2

final area is equal to 4 times of initial area

Á = 4A
