Question

can someone help?
The length of a rectangle is equal to 3 more than
3 times the width. The perimeter is 54 ft. What
are the length and width of the rectangle?

Answer 1

2 times the length plus 2 times the width equals perimeter therefore,
2L+2W= P the length is three times the width therefore, L = 3W and you know the perimeter is 96 and inserting 3w for length you get, 2(3W)+2W=96, then 6W+2W=96, then 8W=96. Divide both sides by 8 and you get W=12. The width is 12. And the length is 36.
