Answer 1

$\huge{\bold{\underline{\underline{Question:-}}}}$

If the area of the square is 900cmsq, then find its perimeter.

$\huge{\bold{\underline{\underline{Solution:-}}}}$

Area of square = 900cm²

Also, area of square = (s)²

∴ (s)² = 900cm²

=> s = √900

=> s = 30cm

Now,

Perimeter of square = 4*side

perimeter = 4*30

∴ Perimeter = 120cm

Answer 2

Answer:

Perimeter = 120 cm

Step-by-step explanation:

Area = (side)²

900 = (side)²

(900)¹/² = side

30 cm = side

Perimeter = 4 × side = 4×30 = 120cm
