Lian uses 200 regular paces to walk around a square park.If one pace of Lian measures 40 cm,what is the measure of each side of the park?
Let's focus on the first sentence. "Lian uses 200 regular paces to walk around a square park." We know that Lian walks "around" the square, so we can assume that this is the perimeter, P= 200 (regular paces). (draw a square for reference :) if needed). We know that a square is equal on each of its four sides, so next we can divide the perimeter by four 200/4= 50 regular paces. Now we know that each side of the sides of the square is 50 regular paces.
Next sentence,"If one pace of Lian measures 40 cm,what is the measure of each side of the park" We have everything we need to answer this now. Our goal is to figure out how much each (individual side) measures. Each side is a total of 50 regular paces and each regular pace is measures 40 cm. Now we can multiply 50(regular paces)* 40cm. Final answer is 2000 cm for each side.
200paces/4sides = 50 paces/side.
50paces/side * 40cm/pace = 2000 cm/side.
