Question

Pls help w work!!

The equation P=2(L + W) is used to find the
perimeter, P, of a rectangle based on the length, L,
and Width, W. Which of the following correctly expresses the value of the width?
(a) P - 2L
(b) P - 2L / 2
(c) 2L - P / 2
(d) 1/2 (P-L)

Answer 1

Lets Do

`\\ \sf\longmapsto p = 2(l + w) \\ \\ \sf\longmapsto l + w = (p)/(2) \\ \\ \sf\longmapsto w = (p)/(2) - l \\ \\ \sf\longmapsto \boxed{ \bf \: w = (p - 2l)/(2) }`
