Question

area of a square is 49 cm² . find the perimeter​

Answer 1

Area= l²

49= l²

l= √49 = 7 cm (side)

P= 4•l= 4•7= 28 cm

Answer 2

The answer is 28 cm

$given \: area \: = 49 {cm}^{2}$

Area of square = 49
${(side)}^{2} = 49 \\ side = \sqrt{49} \\ side = 7$

Perimeter of square = 4 × side
=4 × 7
= 28cm
