Answer:
Then the total area is 116 cm^2 which agrees with answer D
Step-by-step explanation:
Notice we need to calculate the area of two rectangles (one larger at the bottom and a smaller one on top)
The Area of a rectangle is the product: base x height
In our case :
Area of Big rectangle = 12 cm x 7 cm = 84 cm^2
Area of smaller rectangle = 8 cm x 4 cm = 32 cm^2
Then the total area is: 84 cm^2 + 32 cm^2 = 116 cm^2
A square with the same perimeter as a rectangle will have larger area.
However, 42 is not divisible by 4, so we can do 10 by 11.
Length = 11, Width = 10, Area = 110
42 / 4 = 10.5
Length and Width = 10.5, Area = 110.25
Answer:
7 quarters 1 nickel
Step-by-step explanation:
7 x.25= 1.75
1.75+ .05= 1.80
Answer:
The system has infinitely many solutions
Step-by-step explanation:
There are no variables left. And the final equation is correct.
It means the system is going to be correct for any value of variables. So there are infinitely many solutions
