The rectangular photo frame has length (3p + 2) cm and breadth (p − 1) cm; the tick marks show the equal opposite sides. Which expression gives its perimeter?

Question

Accepted Answer

(8p + 2) cm. Perimeter = (3p + 2) + (p - 1) + (3p + 2) + (p - 1) = 8p + 2. Adding only the two labelled sides gives 4p + 1; treating -1 as +1 gives 8p + 6.

The rectangular photo frame has length $(3 p + 2)$ cm and breadth $(p - 1)$ cm; the tick marks show the equal opposite sides. Which expression gives its perimeter?
