The perimeter of a small rectangular garden is 14 feet. If the length is thrice the width, find the width and length of the garden.

width=1.75feet Length=5.75feet

Step-by-step explanation:

perimeter(p)=14feet

Length(L)=3xwidth(w)

L=3 x w

P=2xL+2xw

14=2xL + 2xw

Substitute L=3 x w in 14=2xL+2xw

14=2 x 3 x w +2 x w

14=6w+2w

14=8w

Divide both sides by 8

14 ➗ 8=8w ➗ 8

1.75=w

Width=1.75feet

Substitute w=1.75 in L=3 x w

L=3x1.75 L=5.25

Length=5.25feet

Step-by-step explanation:

Tax paid by Chris on $70 worth of souvenirs =5% of 70=$3.5.

Cost of Souvenirs after tax= 70+3.5=$73.5.

Tax paid on prepares food and lodging = 2%+5%=7% of $580=$40.6.

Cost of food and lodging after taxes =580+40.6=$620.60.

Tax on rental car =10%of $620=$62.

Cost of rental car after taxes =620+62=$682.

Total amount spent by Chris= $73.5+$620.60+$682=$1376.10.

Option D.$1376.10.
