Hi,

The length of a rectangle is 7 more than 3 times its widthhighlight_green%28x%29 .
Question states***The perimeter is 38m
2(3x+7m) + 2x = 38m
6x + 14 + 2x = 38m
8x = 24
x = 3m, the width. the length is 16m 3%2A%283m%29+%2B+%287m%29
CHECKING our answer***
2%2A3m+%2B+2%2A16m+=+38m
Wish You the Best in your Studies.
