Answer:

280 metre

Step-by-step explanation:

Distance walked = Perimeter of the park
Perimeter of square park = Side * 4 = 70 * 4 = 280m
So he has walked 280m

Answer:

Side of square park = 70 m

Perimeter of square =  4a

Where a is the side of square

Perimeter of square park =  4 x 70

                                          =  280 m

Thus she travels 280 m in one round

Since we are given that she took three rounds

So , distance traveled by her in 3 rounds =  280 x 3

                                                                    =  840m

Hence  Distance traveled by Shaina if she takes three rounds of a square Park of side 70 m is 840 m
