See picture for solution steps and answer.
The easiest place to start is with the answer. The 3 by 4 rectangle (upper right) is the answer. P = 2(L + W) = 2(4 + 3) = 2*7 is 14.
14 is less than 16.
Now lets find out why the others can't be true.
The upper left has an area of 12 (6*2). So the area is find.
P = 2 * (L + W) = 2* (6 + 2) = 16 This would support the conjecture so it is not the answer you want.
The lower left has an area of 12 and a perimeter of 2*(12 + 1) = 26. That supports the conjecture. So you don't want that one either.
The lower right does not have an area of 12. It cannot help us at all.
The answers are choices one and three. Hope this helps!
Answer:
44.5
Step-by-step explanation:
Multiplying 10 with 4.45 using mental math to find the total cost of 10 items. first multiply 0 with 445 which will yield 000, then multiply 1 with 445 which will yield 445 now put a cross beneath last 0 in 000 and write 445 before it and perform addition which will yield 4450 as the decimal was initially was before the second last digit in 4.45, place it accordingly in 4450 which will yield 44.5.
