I think it is D, since

P = 2 (l + b)

:2

P/2 = l + b

- l

P/2 - l = b

which can be rearranged by multiplying by 2

which gets you

(P - 2l) = 2b

: 2 again

then you get

1/2 (P - 2l) = b

Rearrange the formula P = 2 (l + b) for b.A) b = (P - 2l) B) b = P/2 - 2l C) b = P/2 + 2l D) b = 1/2 (P - 2l)

Rearrange the formula P = 2 (l + b) for b.

A) b = (P - 2l) B) b = P/2 - 2l C) b = P/2 + 2l D) b = 1/2 (P - 2l)
