Explanation:

Martha likes to walk around a square park.

1 lap is the perimeter of the square, then

2p = 7/10 +7/10+7/10+7/10= 28/10 =14/5 miles or 2.8 miles

3 laps and 1/2 =3.5 laps *14/5 =49/5 miles or 9.8 miles.

She walke around the park 9.8 miles before stopping to rest.

Answer 2

Hey there,
Total distance = 7 / 10 x 4
= 2 4/5 miles
3 times = 2 4/5 x 3
= 8 2/5
1/2 times = 2 4/5 / 1/2
= 5 3 /5
8 2/5 + 5 3/5 = 14 miles

Hope this helps :))
