width = 126
since the length is 3 feet more than thrice we will apply multiplication and addition
thrice it's width meaning 3 times longer
126 x 3 = 378
three feet more which of course means plus three
378 + 3 = 381
she got 5 correct, because fifirsyou have to make common denominators, that would be 30 so for the 1/2 that would be 15/30 or 5/10. im not sure about this answer, but i hope its correct.
