Answer: D. 29 meters

Explanation:

Width is x because it is unknown, and length is 4x-3 as stated.

Since we are looking for perimeter we add all sides.
x+x+4x-3+4x-3=74

2x+8x-6=74

10x-6=74

10x=80

X=8

The we plug in 8 for our x’s.

Width is 8 and length is 4(8)-3, simplified it equals 29.

Length is 29 meters.
