Question:

12345 [234]

Answer:

A. Area in square inches = 1760 square inches

B. Area in square feet = 12.2 square feet

C. 1 square inch = $\frac{1}{144}$ feet

Step-by-step explanation:

Given,

Length of the rectangle (l) = 55 inches

Breath of the rectangle (b) = 32 inches

A. Area of the rectangle = length × breath

⇒ 55 × 32

⇒ 1760 square inches

Area in square inches = 1760 square inches

B. 1 foot = 12 inches

1 inch = $\frac{1}{12}$ feet

1 square inch = $\frac{1}{144}$ feet

∴ 1760 square inches = $\frac{1760}{144}$ feet

⇒ 12.2222 square feet

Area in square feet = 12.2 square feet

C. 1 square inch = $\frac{1}{144}$ feet

Pepsi [2]

Answer:98

Step-by-step explanation:

We can begin by listing the numbers. We get, 74185.... Then, we see that if the original list has 200 numbers, then the next list would have 200/3 numbers, then the next would have 200/9, and so on and so forth. Then, our 2nd list would be like this:3rd number, 6th number,9th number, etc. Then our 3rd list would be :9th number,18th number,27th number... Then, our fourth number would be 27th number, 54th number, 81th number... Thus, our last list would be 81th number,162th number. So now, our problem is simply to find the 81th number and the 162th number, which is quite simple since it is just mod 10, cause it repeats every 10. So, the 81st number is 9 and the 162th number is 8. Thus, our answer is 98!
