Answer:

1376 square centimeters

Step-by-step explanation:

1. Find the total area of the original sheet of paper. It is shaped like a rectangle, and to find the area of a rectangle you multiply the length and the width.

2. 40 x 36 = 1440 sq. cm. This is the area of the unmodified sheet of paper.

3. Now, I'm assuming when you say 4 cm you are referring to each side length of the square. To find the area of a square you square (raise to the power of two) the side length. 4 squared is equal to 16. Each square is 16 square centimeters in area.

4. There are four corners on a sheet of paper. Thus, four 16 sq cm squares will be removed. 16 x 4 = 64.

5. Subtract this value from the total area to find the area of the remaining sheet. 1440-64=1376 sq. cm. is your answer.

I hope you found this helpful. Have a nice day.

(x)+(x+1)+x+2)+(x+3)=216 find 4 consecutive odd integers

lubasha [3.4K]

If it were four consecutive odd numbers then it would be x, x+2, x+4, x+6 and not x, x+1, x+2, x+3. That is just four consecutive integers.

So if you want four consecutive ODD numbers then:

x+x+2+x+4+x+6=216

4x+12=216

4x=204

x=51 so the odd integers would be:

51, 53, 55, 57
