    You firstly want to find the length of the frame. To do this, you would go: \[length = 8 + \frac{ 5 }{ 4 } + \frac{ 5 }{ 4 } = ? inches\]

    Note that 1 1/4 inches = 5/4 inches

    So what would the length of the frame equal to?

    yes 8 + 5/4 + 5/4 = 10 2/4 which can be simplified to 10 1/2 = 10.5 (in decimals). So now we know that the length of the frame= 10.5 inches :) So we have this: |dw:1440590381624:dw| So we want to find the area of the frame right? To do this, we find the area of the BIGGER square first . So Area of Big square = 10.5 times 10.5 = ?
