Find the are of the shape below
skelet666 [1.2K]

Answer:

Area is 235

Step-by-step explanation:

Split the shape evenly so 11 x 14 and 9 x 9then multly and add

when slpitting up the number some times you have to add or subtract so to get 9 x 9 we just take 20 then take away 11 due to the line going through 20 and 20 - 11 = 9

9 x 9 = 81

11 x 14 = 154

81 + 154 = 235

or

Simular to the first one but the cutting line is different. this time the line cuts through 14

9 x 20 = 180

11 x 5 = 55

180 + 55 = 235

On the way home from her friend's house Sandy skateboards 30% of the way, walks 1/2 of the way, and then skips the rest of the w
netineya [11]

Answer:

0.2

Step-by-step explanation:

Convert the walking to percent

\frac{1}{2} \times 100 = 50

Add both skateboarding and walking

30\% + 50\%\\\\= 30 + 50\\\\= 80

Now, subtract that from a whole percent

100 - 80 = 20\\\\20\%

Convert it to a decimal

20\% = \frac{20}{100} \\\\=20 \div 100\\\\= 0.2

Therefore, in decimal, 0.2 is the number that shows the portion of the distance Sandy skips.
