The side of the square ABCD is 6.25 dm. Slide the side of square MNRS if its perimeter is 0.8 the perimeter of square ABCD.

Let us find the perimeter of the square ABCD, knowing the length of its side a = 6.25 dm:

PABCD = 4a = 4 * 6.25 = 25 dm.

Let’s calculate the perimeter of the square MNRS, which is 0.8 of the found perimeter:

PMNRS = PABCD * 0.8 = 20 dm.

Then, the side of the square MNRS b is equal to:

b = PMNRS: 4 = 5 dm.
