Answer:

12 feet x 4 feet

Step-by-step explanation:

The classroom wall is 160 feet, and no more than 30% of it may be covered.

Multiply 160 times .3 to get the maximum amount of square feet that the bulletin board can cover.

You get 48 square feet for the bulletin board.

The length of the board is three times as long as the width, so the length must be 12 and the width must be 4 feet.

Answer: 12 feet x 4 feet

justin=$37.50

Emma=$25.50

to be sure add 37.50+25.50=$63
