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.

Three moons are in the same circular orbit around a planet. The moons are each 120,000 kilometers from the surface of the planet
VladimirAG [237]

Answer:

Step-by-step explanation:

Alright, lets get started.

Please refer the diagram I have attached.

MN is the diameter of the planet which is MN = 60000

AM and NC are the distance of moons from the surface of the planet.

AM = NC = 120000

Since, angle ABC is given as 90 degree, it means, line AC will pass from the diameter of the planet.

So, distance between moon A and moon C is =

AC=AM + MN + NC

AC = 120000+ 60000+ 120000

AC = 300000

Hence the distance between point A and point C is 300000 Km.   :   Answer

Hope it will help :)
