Question

A Square wall clock has a perimeter of 200 cm.(2)

(a) what is the length of the side of the clock?

(b) what is the area of the clock?​

Answer 1

Answer:

(a) perimeter =200

4×S=200

S=200/4

S=40cm

Area of square = S²

=40²

=1600cm²

Answer 2

Answer:

a) 50 cm is the length of the side of the clock.

b) 2500 cm is the area of the clock.

Step-by-step explanation:

a)  Formula of the perimeter of a square = 4 × (length of any one side).

• Perimeter = lenght + length + length+ length

• 200 = lenght + length + length+ length

• length of the side of the clock = 200/ 4 ( number of sides of the square).

• 200/4 = 50 cm

b) Area of a square = length * length

• Area of a square = 50  cm *  50 cm

• Area of a square = 2500 cm
