The square shown is divided into 4 congruent rectangles. If the perimeter of the square is 150 units, what is the perimeter of one of the four congruent rectangles?
Well, find the side length of the square, 150/4=37.5, the four congruent rectangles divide the 37.5 to 37.5/4=
9.375, 9.375+37.5+9.375+37.5= 93.75
Since a square has 4 congruent side lengths. Thus, each side length is 150/4 = 37.5.
As we see from the image, the longer side length of the rectangle is the same length of the square side length. (37.5)
4 of the smaller sides of the rectangle is equal to the length of the square side length (37.5/4 = 9.375)
In each perimeter rectangle, there are 2 long lengths and 2 short lengths.
9.375*2 + 37.5*2 = 93.75.
I hope this helped. :))))
