each side = sqrt (1600/2) ie 28.28 cm
It is a square with lengths of 10 cm
40cm (4 x 10 = 40)
40 cm (10cm x 4 sides = 40cm)
The perimeter is 40cm
Perimeter = sum of the lengths of sides = 5* 7 cm = 35 cm
First, you must find the width. Use Pythagoras' Theorem. Then, just add the lengths of the four sides, to get the perimeter.
The perimeter of 100 square in cm is 40cm. Each side is 10cm, you get 40 when you add the four sides.
P = 160cm
One possibility is 15 x 5 (therefore perimeter is 15 x 15 x 5 x 5 = 40cm).
40 cm is about 15 and 3/4 inches. about 1.7 square feet
The area of a 40 cm square is: 1,600 cm2
