cm*

anonymous · Answer

so let L be the length of the rectangle, and W be the width.
Perimeter = 2L + 2W = 150

L = (W+3)/2

Plug that equation into the perimeter equation to find your answer

anonymous · Answer

whoops, sorry. L = 2*(W+3)

anonymous · Answer

My god, I'm making mistakes everywhere... L = 2W + 3

anonymous · Answer

Sorry about that. Plug L = 2W + 3 into the perimeter equation
150 = 2L + 2W

You can either find the width, and then find the length, or directly find the length by solving L = 2W + 3 for W and plugging that into he equation
