13 multiplied by 20 is equal to 260. This calculation involves multiplying the two numbers together to find the total product. In this case, 13 is being multiplied by 20 to get the final result of 260.
260/500 = 13x20/25x20 = 13/25
To calculate the number of yards needed to cover a 13x20 room, first find the area in square feet: 13 feet x 20 feet = 260 square feet. Since there are 9 square feet in a square yard, divide 260 by 9, which equals approximately 28.89 square yards. Therefore, you would need about 29 square yards of material to cover the room.
To calculate the area of a room that is 13 feet by 20 feet, you multiply the length by the width. So, 13 feet × 20 feet equals 260 square feet. Therefore, the room is 260 square feet in size.
13 x 20 = 260 The area of the floor is 260 square feet. The area of the ceiling is also 260 square feet. The area of the walls can't be calculated without also knowing the height of the room.
The formula for area of a triangle is base times height divided by 2, A=BxH/2 So if you're referring to "20 cm and 13 cm" as the base and height, 13x20=260, 260/2=130, so the answer is 130 square cm. :D
Perimeter is used in several real world situations.For example, if your living room is thirteen feet long and twenty feet wide, you know you can't get a rug whose sides are bigger than 13x20.Another common example is fencing. When you are putting up a fence you don't really care about the area. You are looking for how much fencing you will need, which means you need to know how big the perimeter of the land is.In math, perimeter is used in geometry and trigonometry (among other places), and is sometimes used to help student's practice their algebra skills is middle schools.
