The length of a rectangle is three centimetres more than double the width.
00:00:05.900 --> 00:00:09.810
The area of the rectangle is 27 centimetres squared.
00:00:10.240 --> 00:00:16.090
Write an equation that can be used to find π€, the width of the rectangle, in centimetres.
00:00:17.120 --> 00:00:18.430
Hereβs our rectangle.
00:00:18.890 --> 00:00:21.060
It has a width that we donβt know.
00:00:21.490 --> 00:00:23.110
We also donβt know the length.
00:00:23.790 --> 00:00:26.260
But we do know some information about the length.
00:00:27.010 --> 00:00:30.720
The length is three more than double the width.
00:00:31.420 --> 00:00:34.330
We can write double the width as two π€.
00:00:35.100 --> 00:00:39.720
So we can say that the length equals two π€ plus three.
00:00:40.390 --> 00:00:43.810
The area of this rectangle is 27 centimetres squared.
00:00:44.570 --> 00:00:49.860
We know that the area of rectangles can be found by multiplying the length times the width.
00:00:50.480 --> 00:00:52.360
We know the area is 27.
00:00:53.070 --> 00:01:00.140
27 must equal the length, two π€ plus three, times the width, π€.
00:01:01.130 --> 00:01:08.740
By solving this equation, 27 equals two π€ plus three times π€, we could find what π€ would equal.
00:01:09.670 --> 00:01:16.650
You could also flip the order of the parentheses and have an equally correct equation for solving for π€.
00:01:17.040 --> 00:01:21.470
You could also say 27 equals π€ times two π€ plus three.
