Question

1 po
1.Find the perimeter of square
if each side is 9 m long
O a. 16 m
b. 26 m
O c. 36 m
O d. 46 m​

Answer 1

Answer :

• Perimeter of square is 36m

Given :

• Side is 9m long

To find :

• Perimeter of square

Solution :

Given,

• Side = 9m

As we know that,

• Perimeter of square = 4 × s

where, s is side

》Perimeter of square = 4 × s

》4 × 9

》36m

Hence, Perimeter of square is 36m

More Explanation :

• Perimeter of rectangle = 2(l + b)
• Perimeter Of rhombus = 4a
• Perimeter of triangle = a + b + c
• Perimeter of circle = 2πr
• Perimeter of square = 4s
• Perimeter of parallelogram = 2(a + b)
