Q. 5 find the perimeter of a square whose area is a) 49 cm2
b) 100 cm2
C) 2.56 m2
Answers
Step-by-step explanation:
a) Area of square = (side)^2
49cm^2. = (side)^2
√49 = side
7 cm. = side
Perimeter of square = 4× side
= 4× 7
= 28 cm
b) Area of square = (side)^2
100cm^2. = (side)^2
√100. = side
10cm. = side
Perimeter of square = 4× side
= 4× 10
= 40cm
c) Area of square = (side)^2
2.56m^2. = (side)^2
√2.56. = side
1.6cm. = side
Perimeter of square = 4× side
= 4× 1.6
= 6.4cm
