find the perimeter of the side of square is 36 cm is equal 2 the perimeter of rectangle (i) length of rectangle
Answers
Answer:
The perimeter of a square = 36 cm. Formula used: The perimeter of a square = 4 × a. The area of a square = a 2. Where, a = side. Calculation: According to the question: The perimeter of a square = 4 × a ⇒ 36 = 4 × a ⇒ a = 36/4 = 9 cm. Now, The area of a square = a 2 ⇒ (9) 2 = 81 cm 2. ∴ The area of a square is 81 cm 2

Dear Student,

★ Explanation :
☛ The formula for the perimeter P of a square is given by:
P = 4s
where s is the length of one of the four congruent sides of the square.
∵ Since it's given that P = 36 cm, then we can substitute into the perimeter formula for P in order to find s as follows:
⇒ 36 cm = 4s
⇒ (36 cm) / 4 = (4s ) / 4
⇒(36 cm) /4 = (4 /4) s
⇒9 cm = (1) s
⇒9 cm = s
➤ S= 9 cm is the length of each side of the given square whose perimeter is 36 cm.
