DELMA IS MAKING A PICTURE FRAME. SHE WANTS TO GLUE GOLD BRAID AROUND THE EDGE OF THE FRAME. THE FRAME IS 9IN. x 14IN. WHAT IS THE LEAST AMOUNT OF BRAID DELMA WILL NEED? IF BRAID IS SOLD BY THE YARD AND FRACTIONS OF A YARD HOW MUCH SHOULD DELMA BUY?
I guess the frame is rectangular
and since she's glueing them on the edge then I guess you should take the perimeter which is the sum of the sides: P = 2L + 2W = 2(14) + 2(9) = 46 in She'll need 46 inches. Correct me if I'm wrong ^_^
alina, this is correct also. You just need to finish it off. You know you need 46 inches of braiding. There are 36 inches in every yard, so you'll need \[\frac{46}{36}=\frac{36+10}{36}=\frac{36}{36}+\frac{10}{36}=1+\frac{5}{18}=1\frac{5}{18}yards\]
(46 inches of braid)/(36 inches for every yard) - you need to figure out how many yards fit into 46 inches, which is what I calculated for you above. Does this help?
