A dime weighs 2.268 grams, and a quarter weighs 5.670 grams.
Given: It is given that the length of the painting is 24 inches and the width is 11 inches.
To find: Area of the mat
Solution:
The watercolor painting is 24 inches long by 11 inches wide.
So, the area of the painting is:
The length of painting with mat is = 24 in + 3 in + 3 in = 30 in
The width of painting with mat = 11 in + 3 in + 3 in = 17 in
Now to calculate the area of mat subtracts the area of painting from the area of the mat.
Hence, the area of the mat is 246 in².
1200 times .09 = 108
so $108 interest
1200 +108 = 1308
1308 divided by 18 equals 72.67
so $72.67 a month
