Roco draws two shapes. one of his shapes is 4 times longer and 4 times wider than the other. he found that the perimeter of the
nikklg [1K]

If two squares have different perimeters, the one with the larger perimeter will have a larger area. If two polygons have the same perimeter, then they must have the same shape. If two polygons have the same shape but are different sizes, then they must have different perimeters.

If two squares have equal areas, they will also have sides of the same length. But although "equal areas mean equal sides" is true for squares, it is not true for most geometric figures.

In order to find the perimeter or distance around the rectangle, we need to add up all four side lengths. This can be done efficiently by simply adding the length and the width, and then multiplying this sum by two since there are two of each side length.

aisha used six boards on each of the birdhouses she made .which experssion represents the total number of boards she would need
insens350 [35]
Well normally you would have to know the amount of birdhouses that she made. But if not, then it would be multiplying 6 times the number of n the amount of birdhouses that she made. Not sure if this is making sense. but if there are 6 boards for N (each of the bird houses) then the answer would just be 6n which is 6 times n
