So we're given 12, 13 different questions that have to do with, it looks like perimeter, parallelograms, squares, area, trapezoids, so all these different concepts.
00:12
And so we're just going to kind of run through each of the questions.
00:15
We're going to start on question three because the first two questions that were given to us were correct.
00:19
But question three was answered and it was not correct.
00:21
So you have a square table and one side measures three meters and they want to know what's the area of the table.
00:28
Well, if you have a square, all the sides are the same.
00:31
And so the area of the table would be three times three or nine square meters.
00:37
Question number four, so you've got a classroom, and it's five meters by four meters.
00:43
Find the area.
00:44
Area is length times width.
00:45
Five times four is 20.
00:47
So we have 20 square meters of area in that classroom.
00:52
A rectangular covered court has an area of 120.
00:56
So now they're giving me the area of 120 meters, and they give us a width of 10 meters.
01:01
And we want to work backwards to find the length.
01:03
So if i have the area, i'm going to work backwards by dividing by 10.
01:06
So 120 divided by 10 tells me that the length is equal to 12 meters.
01:15
Number six.
01:17
So how do we solve the area of a parallelogram? well, a parallelogram could be like a rectangle.
01:22
It could be offset.
01:25
But regardless of what the shape is, it's just the base times the height or the length times the width.
01:31
And so the options that they give us is the product of the base and the height.
01:35
So c, the product of the base in the height.
01:38
A triangular pond has a base of 10 and a height of 6.
01:41
What's the area? well, a triangle's area is half the base times the height.
01:45
So half of 10 is 5.
01:47
5 times 6 is 30, so 30 square meters would be the area of that triangle.
01:54
8 is also the area of a triangle, but it has a base of 12 and a height of 8.
01:58
So half of the base.
01:59
So half of 12 is 6, 6 times 8 is 48.
02:02
So 48 square meters...
