The circumference of a rectangle is 40 cm, the length is 12 cm, and the width is how many cm?

The circumference of a rectangle is 40 cm, the length is 12 cm, and the width is how many cm?


40 △ 2-12 = 8 cm
The width is 8 cm



The circumference of a rectangle is 20, the length is a, and the width is ()
A. 10-aB. 20-2aC. 10-2aD. 20-a


If the circumference of the rectangle is 2 (length + width), then the width is 202-a = 10-a



The width of a rectangle is 12 cm and the length is 125% of the width. After dividing its area into 2:3, find the perimeter of the larger rectangle


Length: 12 * 125% = 15
It can be divided into two situations
1. Length of larger rectangle = 15 * 3 / (2 + 3) = 9
9*2+12*2=42
2. Width of larger rectangle = 12 * 3 / (2 + 3) = 7.2
7.2*2+15*2=44.4



The circumference of a rectangle is cm. How many cm is its width?


The width is C / 2-AM
