Answer:
The sides could be: (1,18); (2,9) or (3,6)
Step-by-step explanation:
We are given that the area of the rectangle is 18cm² and the sides are whole numbers.
Area of rectangle is product of its sides.
This means that we need to find pairs of whole numbers whose product is 18.
Now:
18 = 1x18
18 = 2x9
18 = 3x6
Hence the sides could be 1 and 18; 2 and 9; or, 3 and 6.
(All sides are in cm)
