변의 길이가 10cm 인 정사각형이 있다.

그리고 그 정사각형에 한 변의 1/3 간격(2.5cm 간격) 으로 점을 찍고

그 점 중 1번째 점들. 즉

.      .      .      .

.                    .

.                    .

.      .      .      .

빨간 점에서 서로 이웃한 빨간 점끼리 선을 그었을 때,

정사각형 안에 작은 정사각형이 하나 생기게 된다.

문제- 여기서 큰 정사각형의 넓이는 작은 정사각형의 넓이에 몇 배인가?

(소수점 아래 1번째 자리에서 반올림)

풀이 필수

 

+보너스 문제(안 풀어도 됨)(풀면 해결 2개)- 그럼 아까와 같은 과정으로 1/4지점에 점을 찍어서 만들어진 사각형의 넓이는

1/3지점에 점을 찍어서 만들어진 사각형의 넓이에 몇 배인가

(소수점 아래 1번째 자리에서 반올림)

풀이 필수 22
