A picture is 1 in. longer than it is wide. It is put into a frame 1/2 in. wide. If the area of the frame intself is 8 in.2, how big is the picture?
(l + 2) (l + 1) -(l + 1) (l) = 8in.2
LSquared + l +2L -LSquared -l =*inSquared
2l = 8in Squared
l = 4
l + 1= 5
This is the wrong answer. the correct answer not 4 by 5 but 3 by 4.
Please show me how to get the correct answer.
