Question #2d17c

1 Answer

Dec 26, 2016

The length $= 7$ $=7$ inches

Explanation:

$2 w + 2 l = 26$ $2w+2l=26$

$2 (6) + 2 l = 26$ $2(6)+2l=26$

$12 + 2 l = 26$ $12+2l=26$

$2 l = 26 - 12$ $2l=26-12$

$2 l = 14$ $2l=14$

$l = 7$ $l=7$ inches

substitute w= 6 and l = 7

$2 (6) + 2 (7) = 26$ $2(6)+2(7)=26$
$12 + 14 = 26$ $12+14=26$

$26 = 26$ $26=26$
