Question

The area of a square is 81cm2
a) What is the measure of the side of the square?
b) Calculate the perimeter of the square.

Answer 1

Answer:

a. 9cm

b. 36 cm

Step-by-step explanation:

a. root over of 81 cm^2 =9cm

b. perimeter of a square =4× side

4×9=36

Answer 2

ANSWER:

• Side of square = 9cm
• Perimeter of Square = 36 cm

GIVEN:

• Area of square = 81 cm²

TO FIND:

• Side of square
• Perimeter of Square.

SOLUTION:

Formula

Area of square = (side)²

=> (Side)² = 81 cm²

=> side = √81

=> side = 9 cm

Formula

Perimeter of Square = 4(Side)

=> Perimeter = 4(9)

=> Perimeter = 36 cm

NOTE:

• Area of rectangle = length*Breadth
• Area of square = (side)²
• Perimeter of a square = 4(side)
• Perimeter of rectangle = 2(length+breadth)
