I would answer this but I am not sure
Answer:
Area: 1,200 square centimeters. Perimeter: 140 centimeters.
Step-by-step explanation:
Since you have to multiply the length and width in order to find the area, multiply 30 and 40 together and you can find 1,200. Next, to find the perimeter you have to add all the lengths of the rectangular swimming pool, which will result in 140 centimeters.
For this question you can first divide by 2:
(12÷2)/(64÷2) so you will have 6/32 and then you can divide by 2 again so you will have 3/16 and that's the simplest form :)))
