What is the area of the polygon shown below?

Mathematics
1 answer:
Radda [10]3 years ago
3 0

Answer:

66

Step-by-step explanation:

first you find the area of the rectangle

5*12=60

then you find the area of the triangle

to find the length of the dotted line you need to subtract 9 from 12 which is 3

to find the length of the line adjacent to the dotted line you need to subtract 5 from 9 which is 4

use the triangle area formula 3*4*1/2=6

add the areas of the triangle and the rectangle 60+6=66

United Express, a national package delivery service, charges a base price for overnight delivery of packages weighing 1 pound or
jonny [76]

Answer:

The correct answer is the base price is $14.50 and surcharge is $2.45 per pound.

Step-by-step explanation:

United Express charges a base price on packages weighing less than or equal to 1 pound and a surcharge for additional pounds.

Let the base price be $b and surcharge be $s.

For a 4 pound package, the customer is billed $21.85. Therefore the equation of his billing looks like b + 3s = 21.85.

For a 19 pound package, the customer is billed $58.60. Therefore the equation of his billing looks like b + 18s = 58.60.

Subtracting both the equation from each other we get 15s = 36.75

⇒ s = $2.45 and b = $14.50.

Thus the base price is $14.50.
