Question

a square sheet paper has a perimeter of 40 cm what is the length of its side also find the area of the square sheet.​

Answer 1

Answer:

perimeter = 40 cm

therefore the length,

perimeter = 4*a

P = 4 *a

40 = 4 *a

10 = a

therefore length of the square = 10 cm

now area of the square,

side * side = area

10 * 10 = 100 cm²

therefore the area of the square = 100 cm²

Answer 2

Perimeter of a square = 4 × length of its side

40 = 4 × length of its side

length of its side = 10 cm

Area of the square sheet = 10² = 100 cm²
