Answer 1

Answer:4a*5

=4*70*5

=1400

Step-by-step explanation:

Answer 2

Sapna walks 1400m in all.

It is given that Sapna walks around a square park whose side is 70m.

We know that for a square of side 'a', its perimeter is given as 4a.

So, for the square park of side 70m, its perimeter is

= (4*70) m

= 280m

So, after walking 1 time, Sapna would cover 280m in total.

Similarly, after walking 5 times, Sapna would cover 5 times the perimeter.

It is equal to (5*280) m

= 1400m
