Algebra.Com's Answer #621210 by addingup(3677)![]() ![]() You can put this solution on YOUR website! The area of the lawn which I will call x is L*W-S^2, where S^2 is the area of the square sand box. Using the numbers in the problem: \n" ); document.write( "x= (79 1/3*72)-(3.5^2). Let's solve the first parenthesis: \n" ); document.write( "79 1/3 Convert this mixed number to a fraction: \n" ); document.write( "(79*3)+1= 237+1= 238. So, our number is 238/3 \n" ); document.write( "-------------------------- \n" ); document.write( "238/3*72= 238/3*72/1= (238*72)/(3*1)= 5712 is the total area. Now let's deduct the sandbox: \n" ); document.write( "5712-3.5^2= 5712-12.25= 5699.75 is the area of the lawn \n" ); document.write( " |
