Answer:
14 cm
Step-by-step explanation:
One side of the composite has a length of 6 and the other side has a length of 8.
If we add these two numbers, we'll get the missing side length of the rectangle
6 + 8 = 14 cm
Answer:
22221
Step-by-step explanation:
I set up the problem like this
823
x27
Then I multiplied 7 by 3 and carried over the one and then multiplied 7 by 2 and added one and carried the one over... I then multiplied 7 by 8 and added the one!
Then I put a zero where the 7 I first multiplied would be... I then multiplied 2 by 3 and then multiplied 2 by 2 and finally multiplied 2 by 8!
I then added up the two values! (Sorry this probably sounds confusing!)
