50 keep that in mind
Then put 50 into a ratio of 1% which equals 0.5 (work~ 50 x 1% = 0.5)
1% = 0.5
Times by 30 which equals 1 (0.5 x 30 = 15)
So 30% of 50 = 15
He will reach first base 15 times
Formula for perimeter of rectangle: P=2(L+w) P=2L+2w Here Perimeter, p= 72 ft And scale factor of length and width=3.5 which means rectangle is enlarged. So perimeter of rectangle= 3.5 x 72 P=252ft
