Algebra.Com's Answer #367295 by IWork4Dessert(60)![]() ![]() You can put this solution on YOUR website! What do you know about rectangles? In order for a shape to be a rectangle, it has to have two pairs of equal sides. You can start by drawing one up(I'm afraid I can't draw one in this text box, so bear with me). \n" ); document.write( "First of all, you know that the length of one of the sides is 5. But if a rectangle has two pairs of equal sides, then the length opposite that one will be 5 as well. Go ahead and label those. \n" ); document.write( "Now. You know that the perimeter is 36. Perimeter is all of the sides added together. The sides we don't know the lengths of are going to be equal too, like I said above. Two of the sides together(5+5) are 10. Your equation: \n" ); document.write( "36=10+2x \n" ); document.write( "Now subtract 10 from both sides(remember, you're trying to get the variable--the letter--alone). \n" ); document.write( "26=2x \n" ); document.write( "Divide both sides by 2 to get the variable by itself. \n" ); document.write( "13=x \n" ); document.write( "Since the problem is asking for the area, all you have to do is multiply the short side(5) by the long side(13). \n" ); document.write( "5x13=65 \n" ); document.write( "65 inches squared \n" ); document.write( " |
