Answer:

Total Area = 108 cm^2

Step-by-step explanation:

Area Trapezoid

<em><u>Givens</u></em>

b1 = 6cm

b2 = 12 cm

h = 6cm

<em><u>Formula</u></em>

Area = 1/2 (b1 + b2)*h

<em><u>Solution</u></em>

Area = 1/2 (6 + 12)*6

Area = 1/2 18*6

Area = 54 cm^2

Triangle

<em><u>Givens</u></em>

b = 12 cm

h = 15 - 6

h = 9

<em><u>Formula</u></em>

Area = 1/2 * b * h

<em><u>Solution</u></em>

Area = 1/2 * 12 * 9

Area = 54 cm^2

<em><u>Total Area</u></em>

Total Area = 54 + 54 = 108 cm^2

Hello from MrBillDoesMath!

Answer:

108 cm^2

Discussion:

The area of the logo  =

area of Trapezoid on top (I)  + area of triangle on bottom (II)

I  = (1/2) h ( b1 + b2)            h = altitude, b1, b2 = bases

  = (1/2)  6  ( 6  + 12)

  = (1/2) 6 ( 18)

  = 54

II  = (1/2) b h

   = (1/2) (12) ( 15 - 6)               => altitude of triangle = 15 - 6 NOT (1/2) 15

   =  54

I + II= 54 + 54 = 108

Thank you,

MrB

According to the key of a particular park map, every 8 inches on the map represents 3 miles of trails in the park. How many inch
MA_775_DIABLO [31]

Answer:

24 inches represents 9 miles in the map

Step-by-step explanation:

To solve this problem you take into account that 8 inches represents 3 miles and that x represent the number of inches for 9 miles. That is:

8 ------- 3

x ------- 9

This is simply a rule of three, then you calculate:

x=\frac{8\ x\ 9}{3}=\frac{72}{3}=24

Hence, 24 inches represents 9 miles in the map
