Question

Find the area of a square with a perimeter of 76cm

Answer 1

Answer:

361 cm^2

Step-by-step explanation:

  From the properties of square :

     Perimeter of square is 4a

    Area of square is a^2

 *where a is the length of side of that square.

Here, let the side-length of the square be A.

 ⇒ Perimeter = 76 cm

 ⇒ 4A = 76 cm

 ⇒ A = ( 76 / 4 ) cm

 ⇒ A = 19 cm

Hence,

     Area of the square should be :

             ⇒ ( 19 cm )^2

             ⇒ 361 cm^2

Answer 2

Answer:

we know that

perimeter of square 4*side

so putt value then 19 cm of each side

then area of square is 361 cm^2
