Answer:
Answer - 160
Step-by-step explanation:
2L+2W = 430
L = 3W-5
2(3W-5)+2W = 430
6W-10+2W = 430
8W = 440
W = 55 and L = 3(55)-5 = 160
Answer:
Length = 160 and width = 55 yards
Step-by-step explanation:
Perimeter = 2L + 2W where L = the length and W = the width.
L = 3W - 5 (given).
So substituting for L is the formula for the perimeter:-
2(3W - 5) + 2W = 430
6W - 10 + 2W = 430
8W = 440
W = 55 yards.
So the Length L = [430 - 2(55]) / 2 = 160 yards.
