Question

Paola wrote the following equation for the perimeter of a rectangle p =2(l+w)

Which equation is equivalent to the equation Paolo wrote?

A. W=P-2l
B. W=P-I
C. W=P-2I/2
D. W=P+2l/2

Answer 1

C. W = (P-2I)/2

Explanation:

The given equation can be solved for W this way.

P = 2l +2W . . . . eliminate parentheses

P -2l = 2W . . . . subtract 2l

(P -2l)/2 = W . . . divide by 2

The appropriate choice is ...

W = (P -2l)/2

_____

Please note that parentheses are required in plain text. In typeset form, the fraction bar acts as a grouping symbol.

`W=(P-2l)/(2)`
