Answer:

$167.20

Step-by-step explanation:

0.18 x 130 = $32.4 (this is what they tipped)

the total now stands at $153.4 before tax

now to work out the tax you multiply the decimal of 9% by $153.4

0.09 x 153.4 = 13.8

the total cost of the meal is $167.20

Area by Heron's formula:
semiperimeter = (15 + 20 + 25)/2 = 60/2 = 30 cm

Area = \sqrt{30(30-15)(30-20)(30-25)}= \sqrt{30 \cdot5\cdot10\cdot15}= \\\\ {} \ \ \ \ \ \ =\sqrt{22500} =150 \ cm^2

The formula of the area of a triangle: Area = 1/2 * base * height
1/2 * 25 * height = 150
12.5 * height = 150
height = 150/12.5
height = 12 cm
