The lenght of a painting is 2 inches longer than the width. the area is of the painting is 48 in2. if a 3 inch frame is put around the painting what is the area of the frame

First, divide 48 in half

48/2 = 24

Then take 2 away from 24

24-2 = 22

Now add the 2 to the other 24

24+2 = 26

Divide 22 and 26 in half

26/2 = 13 (the length of one side)  22/2 = 11 (the width of one side)

Get the area of the painting using a=lw

13*11 = 143

Now, save that area for later and find the length and width of the frame by adding three to both numbers

13+3 = 16 
11+3 = 14

Get the area of 16 and 14

16*14 = 224

Finally, subtract 143 from 224

224 - 143 = 81

81 is the area of the frame

I hope this helps you!

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
