Of 640 square centimeters.
00:03
What is the base if the height is 32 centimeters? so to find the area, you're doing base times height divided by 2.
00:09
So the area is 640, and the base, i'm sorry, the height is 32, so 32 times b divided by 2.
00:21
So the first thing i'm going to do is i'm going to multiply both sides by 2.
00:25
So the 2 is cancel out here.
00:27
In 2 times 640 is 1 ,280 equals 32b and then i'm going to divide by 32 to get the b by itself so divided by 32 in b equals 40 sorry you just didn't have enough room kind of cramped okay two squares are put side by side to form a rectangle.
01:05
The side of the square measures five centimeters.
01:07
What is the area of the rectangle? okay, so here's my square.
01:10
They're five by five.
01:12
And then i'm going to put another square right next to it, not drawn to scale, five by five.
01:17
And it wants to know the area of now the rectangle.
01:21
So five plus five is ten.
01:23
So it's ten is the length and five is the width.
01:26
So to find the area of a rectangle, you're going to do length times width.
01:31
So you're going to do ten times five.
01:33
Which is 50 centimeters squared...
