Answer:
Get a calculator
Step-by-step explanation:
Most of the time for simple math like multiplying 2 digits, it is easiest if you just get a calculator. It saves a lot of time.
If you can't get a calculator then i recommend memorizing some common equations.
For example 10*15= 150
so that if you get 12*15=?, you can easily just add two extra 15's to your answer of 150.
15+15 is 30, and 30+150(from 10*15)=180.
Therefore 12*15=180.
:) Hope that helped!
Answer:
11.5 square units
Step-by-step explanation:
It’s a 4 by 6 rectangle, so the total is 24. Then subtract the three little triangles on the outside. (Much easier than doing the main triangle).
1/2x1x4=2
1/2x1x6=3
1/2x3x5=7.5
2+3+7.5=12.5
24-12.5=11.5
