- [Instructor] The parallelogram shown below has an area of 24 unit squares, square units.
아래 주어진 평행사변형의 넓이는 24 ㎠입니다
Find the missing height.
높이는 무엇일까요?
Here's the parallelogram.
평행사변형을 봅시다
This side has length six. This side has length five.
이 변의 길이는 6 ㎝이고 이 변의 길이는 5 ㎝예요
We want to find the missing height
이 평행사변형의 높이는 무엇일까요?
and they gave us the area.
평행사변형의 넓이가 주어졌죠?
So pause this video and see if you can figure it out on your own.
동영상을 잠시 멈추고 직접 풀어 보세요
The key to solving this is to realize
이 문제의 핵심은
how the area relates to a base and a height.
넓이, 밑변, 높이의 상관관계를 아는 것입니다
An area of a parallelogram, area of a parallelogram is going to be equal
평행사변형의 넓이는
to the base times the height.
밑변 · 높이입니다
Now what's the base in this scenario?
이 문제에서 밑변은 무엇일까요?
You could do this length right over here as the base.
이 길이를 밑변이라고 볼 수 있겠죠
Which is also going to be the same as that length.
이 길이는 윗변의 길이와 같을 것입니다
In a parallelogram opposite sides have the same length.
평행사변형은 마주보는 변의 길이가 같습니다
The parallel sides have the same length.
평행하는 변끼리 길이가 같죠
So this is going to be six.
그러므로 이 변의 길이도 6이 됩니다
Our base is going to be six.
그러므로 밑변의 길이는 6입니다
Our height is what we want to figure out.
여기서 높이를 구해야 합니다
I will just write this as the h that we're trying to figure out.
높이는 h이므로 여기에 써 볼게요
We know the area.
넓이를 알고 있죠?
The area is 24 square units.
넓이는 24 ㎠입니다
There we go.
따라서 식은
We have 24 is equal to six. Is equal to six times the height.
24 = 6 · h입니다
Six times what is equal to 24?
6에 어떤 수를 곱해야 24가 될까요?
Six times four is equal to 24.
4를 곱하면 24가 되겠죠
We know that h is going to be equal to four units. H is equal to four units.
따라서 h는 4 ㎝입니다
