Question

A square sheet of paper has a perimeter of 40 cm. What is the length of its sidel Also
the area of the square sheet?
​

Answer 1

given,

perimeter = 40 cm

therefore the length,

perimeter = 4*a

P = 4 *a

40 = 4 *a

10 = a

therefore length of the square = 10 cm

therefore length of the square = 10 cmnow area of the square,

side x side = area

10 x 10 = 100 cm²

therefore the area of the square = 100 cm²

Answer 2

Step-by-step explanation:

Here we think that the length of the paper is x cm

then,

• 4x=40
• x=40/4

x=10cm

Finally,the area of the square is=(10)²cm²

=100cm²
