Answer:
Formula for
the perimeter of square = 4side eq 1
area of square = (side)² eq2
Explanation:
1 2m 10 cm ( 210cm)
the perimeter of this square = 4 × side
4× 210cm = 840 cm (8m40cm)
the area of this square = side ×side
210 cm ×210 cm = 44100 cm square
or 4.41 meter square
1 side 5 m
the perimeter of this square = 4 × side
4×5m=20m
the area of this square = side ×side
5m×5m=25meter square
(i) 4.2 cm
the perimeter of this square = 4 × side = 4×4.2cm=16.8cm
the area of this square = side ×side= 4.2 cm ×4.2cm = 17.64 cm square
(iv) 250 mm
the perimeter of this square = 4 × side = 4×250mm =1000mm
the area of this square = side ×side= 250mm ×250mm =62500 mm sq.
