A rectangle has a length that is 3 times the width. Use the formula P = 2l +2w to determine the length if the perimeter is 32 and the width is 4 a. 12 c. 32 b. 8 d. 4
Let the width be 4 Let the lenght be 3x because it is 3 times the width P = 2L + 2W 32= 2(3X)+2(4) Combine like terms 32 = 6x+ 8 solve for x 24=6x divide x= 4 Answer: D
