15x21=315
The LCM of 15 and 63 is 315 63x5=315 15x21=315.
The grid strategy of 15x21 involves breaking down the multiplication into more manageable parts using a grid or area model. You can split 15 into 10 and 5, and 21 into 20 and 1, creating a 2x2 grid that calculates the products: 10x20, 10x1, 5x20, and 5x1. This results in 200, 10, 100, and 5, respectively. Adding these products together gives the final answer of 315.
Just take the square footage and divide it by nine(9). For example; if your living room is 12x12 and your den is 15x21 then you would multiply 12x12=144, then multiply 15x21=315, add the two 144+315=459, then divide by 9, 459/9=51 total sq yrds. In order to get the square yardage for a role of carpet(12ft WIDE) all you have to do is take the length and multiply it by 1.33 and you will get the sq yrds. For ex. if you have a role 12x 223ft you just multiply 223x1.33=296.59yrds.
To find the area of a room, multiply its length by its width. For a room that measures 15 feet by 21 feet, the area is 15 x 21 = 315 square feet. Therefore, the room is 315 square feet in size.
