We know that a rectangle is dilated by a factor of 1/5 which means that the area of a rectangle is dilated by a factor of 1/25. I get 1/25 because each side was dilated by a factor of 1/5, so I just need to take 1/5×1/5=1/25 as the factor of area if rectangle. Then, the new rectangle is 4 square yards, so we just need to find the area of the old or pre-rectangle. Furthermore, we know that the pre-rectangle is 25 times bigger than the new rectangle based on what we did above, so the area of the pre-rectangle is: 4×25=100 square yards. However, the question asked us to find the possibility dimension of the original images. Area of the rectangle= length× width 100 square yards length=20 yards, width=5 yards length=100 yards, width=1 yard length=25 yards, width=4 yards. Hope it help!
