Answer :
A= 42in²
P = 2l + 2w so
(21 x 2) + (2 x 2)
42 + 4 = 46
46 = 21 by 2
Now let's do 6 and 7
(6 x 2) + (7 x 2)
12 + 14 = 26
46 > 26
so 21 by 2 has greater P (perimeter)
P = 2l + 2w so
(21 x 2) + (2 x 2)
42 + 4 = 46
46 = 21 by 2
Now let's do 6 and 7
(6 x 2) + (7 x 2)
12 + 14 = 26
46 > 26
so 21 by 2 has greater P (perimeter)
