Answer:
90 meters squared
Step-by-step explanation:
First you multiply 10*4.5=45
Then you multiply 45 and 2 because 1cm=2m
45*2=90
If we add the interior and the exterior of the corner of a triangle we always get 180 degree
Answer:
With Riley's pattern, he will practice 2,000 total minutes in 25 days.

We have to find the mass of the gold bar.
We have gold bar in the shape of a rectangular prism.
The length, width, and the height of the gold bar is 18.00 centimeters, 9.21 centimeters, and 4.45 centimeters respectively.
First of all we will find the volume of the gold bar which is given by the volume of rectangular prism:
Volume of the gold bar 
Plugging the values in the equation we get,
Volume of the gold bar 
Now that we have the volume we can find the mass by using the formula,

The density of the gold is 19.32 grams per cubic centimeter. Plugging in the values of density and volume we get:
grams
So, the mass of the gold bar is 14252.769 grams
