12,180

Step-by-step explanation:

9*3=27

3*2+2=8

x out the 3 and add a 0

5*9=45

5*2+4=14

so it is 87 * 140= 12,180

it happens during combustion and impacts the environment because the plants and trees take in that and it can cause them to die.

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
