Question

Jerome uses metal strips to make rectangular frames that are 8 inches long and 4 inches wide. What is the total length of the metal needed to make 5 frames?

A. 17 inches
B. 60 inches
C. 120 inches
D. 160 inches

Answer 1

You add the lengths,
8+4+8+4 to get one frame ( 2{8+4}) which equals 24 inches
Then multiply that by 5,

24 X 5 = 120 inches

Answer 2

total length for a frame is 2*(8+4) which would be 24inches
so in order to make 5 of them,it would be 24*5=120inches
