A rectangle with an area of 18 cm2 was divided into 9 equal strips, what is the area of each strip?

Assuming that the rectangle is 18 cm square. is with the parties:
length – 9cm and width 2cm.
So, when dividing it into 9 equal strips, one strip will turn out with sides:
length – 2 cm and width 1 cm
So S = axb
S = 2×1 = 2 cm square.
Second option:
From the condition knowing that the area of the rectangle is 18 cm square.
And divide it into 9 equal parts, then
18: 9 = 2 cm square.
Answer: the area of the strip is 2 cm square.
