The width of the rectangle is 8 inches, which is 1/3 of its length. Find the perimeter and square the rectangle.

1) Let us find out how long the rectangle given to us has, if it is known that its width is 1/3 of its length, and its width is 8 dm.

8 * 1/3 = 24 dm.

2) We find out what perimeter a given rectangle has, if it is known that its width is 8 dm, and we found out the length and it was 24 dm.

(8 + 24) * 2 = 64 dm.

3) Let’s find out what area the rectangle has, if its sides are known and they are 8 dm and 24 dm.

8 * 24 = 192 dm².

Answer: the perimeter of the rectangle is 64 dm², and its area is 192 dm².
