Question

Solve this problem using the proper formula. A carpenter is building a bookcase the perimeter of the top is 108 in. What length must the stock be if the width is 8 in.? The shelf is inches long.

Answer 1

It is 46! DILLY DILLY COMRADES!

Answer 2

Assuming the length is y and the width is x
Perimeter = y + y + x + x
= 2y +2x
= 2 (y + x)
if the is 8 and the perimeter is 108
108 = 2 (y +8)
108/2 = y+8
54 = y +8
54 - 8 = y
46 = y

Length = 46 inches
