hey user!!
your answer is here...
first of all, we have to find the perimeter of the rectangular park.
given :- b = 450ft and h = 200ft
perimeter of the rectangular park = 2(450+200)
= 2 × 650
= 1300ft
we know that 12 inches = 1 foot
therefore 24 inches = 2ft
so her each step is 2ft long
hence, no. if steps she will take to walk around the rectangular park = perimeter of the rectangular park/length of her each step
= 1300/2
= 650
final answer - SHE WILL TAKE 650 STEPS.
cheers!!
