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.
300ft cause A=lw and it said its a square so all sides are the sam
so
300 times 300 = 900

1/1-1/4-3/5= (money spent)
1×4×5/(1×4×5)-1×1×5/(1×4×5)-3×1×4/(1×4×5)
20/20-5/20-12/20
(20-5-12)/20=3/20
