Answer: 540
Step-by-step explanation:
2.5 x 3 is 7, so if he travels at the same rate, you must increase the miles by the same amount. So in this case its 180 x 3, which is 540.
First we have to find the perimeter. Which is for rectangles 2(l+w)
that means the perimeter is 75.84 ft
each slat is apparently half a foot which would be 0.5ft
then you simply divide 0.5 from 75.84 and round it to the nearest whole number.
