Question

the length of a new rectangular playing field is 8 yards longer than triple the width.if the perimeter of the rectangular playing field is 344 yards, what are the dimensions?

Answer 1

2l + 2w = 344

2(3w+8)+2w = 344

6w+16+2w=344

8w=328

width=41

Then plug back into the perimeter equation

2l + 2(41)=344
2l + 82 = 344
2l= 262
length=131
