Answer: the dimensions are 5 and 7(7 as the length and 5 as the width)
Explanation:
Find a way to make a rectangle that would have the perimeter of 24( 7 as the length and 5 as the width). Do 7x5 and that’ll give you 35. 30-35 is 5, so that’s the width, 5.
I’m very sorry if that didn’t make any sense
