The length of a rectangle is six feet greater than the width. the perimeter is 168 feet. What are the dimensions of the rectangle?

45 feet by 39 feet

Step-by-step explanation:

l = length

w = width

Perimeter, p of a rectangle = 2( l + w)

and p = 168 feet

but l = 6 + w

substitute the value of l

168 = 2(( 6 + w) + w)

168 = 2( 6 + w +w)

168 = 2(6 + 2w)

expand

168 = 12 + 4w

subtract 12 from both sides

168 - 12 = 4w

156 = 4w

divide both sides by 4

39 = w

substitute the value of w in  l = 6 + w

l = 6 + 39

l = 45

Hence, the dimensions are 45 feet by 39 feet

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
