Determine the area of a rectangle whose diagonal is 24cm and the angle between the diagonal is 60deg.

Consider, ΔBCD, in rectangle,

cos 60 = b/24

1/2 = b/24

b = 12

Now, Sin 60 = p/24

√3/2 = p/24

p = 24√3/2 = 12√3

Area would be : Length * Width = 12 * 12√3 = 144√3 cm²

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
