Answer:
320m
Step-by-step explanation
a rectangle has four sides, two pairs of identical sides. So two sides are 16. So that adds up to 32. Perimeter is all sides added together. so it has to add up to 72. 72 minus 32 is 40, so two of the sides have to be 40. Area is length times width, so 16 times 20, which is 320.
Here is how we are going to find the answer. Firstly, we need to know what is 4/5 of an hour. An hour has 60 minutes. So we divide 60 by 5 which is 12 and multiply this by 4 and we get 48 minutes. Since it took Hailey 1/8 the time it took Joel to do his chores, now we are going to know what is 1/8 of 48 minutes. We divide 48 by 8 and we get 6. Since it is only 1/8, therefore, the time that Halley took to do her chores is only 6 minutes. Hope this helps.
