Q.
A rectangle has a width of 43cm and a perimeter of 194cm What is the​ rectangle's length?


* A:
P = 2L + 2W 194 = 2L + (2 x 43) 194 = 2L + 86 108 = 2L L = 54 cm

* A:
(194 - 43 - 43)/2

* A:
W = 43 P = 194 L = P/2 - W = 97-43 = 54 cm

* A:
54 cm. Now all you have to do is work out how I got that answer.

* A:
It’s length is about 40 feet
