A diagram helps.
Diagonal TO divides the rectangle into two triangles of base 10 and height 4. The area of the two of them together (the area of the rectangle) is 10*4 = 40.
The area of rectangle TYOC is 40 square units.
Answer:
The difference between combinations and permutations is that in permutations, the order matters, while it doesn't with combinations. For example, if you are given 5 numbers (1,2,3,4,5) and you have to determine how many 3 digit numbers you can make, that is a permutation question because 123, 231, 321, etc. are all different numbers. If, for example, we have to find how many ways three people can be chosen out of a group of 5, that is a combination question and you must use the combination formula as the order of the three people does not matter. Other than the order, combinations and permutations are the same

I found this question while scrolling through Mathematics, which is not where it belongs. I feel it would best fit in Arts. Or even History if you were unsure, would've been a better choice than Mathematics.
Answer:
A) r=2t
B) 4
t²
C) 4(30)² which will end up being 11310 in²
Step-by-step explanation:
A) If it increases 2 inches every minute, you would take that and put it with the t, aka time.
B) A=r² which will translate into A=(2)²
C) You take the half-hour, which is 30 minutes, and translate that into t then place that into your calculator and get an answer of 11,309.73 and then round up to the whole number
