Question

find the square of a square whose parameter is 276 mm​

Answer 1

Step-by-step explanation:

Let sides of square be a

we know that,

perimeter of square =4a

⇒276 = 4a

a = 276/4

a = 69

Now,

Area of square is equal to ( side )²

69² = 4761 mm²

Answer 2

Answer:

4761 sq mm

Step-by-step explanation:

square of perimiter = 276 mm

4× side = perimeter of square

4 × x = 276

x = 276/4

x = 69 mm

side of square (x) = 69 mm

Area of square = side × side

= 69 × 69

= 4761 sq. mm
