the length of each side of square a is increased by 100 percent to make square b . if the length of the side of square b is increased by 25 percent to make square c , by what percent is the area of square c greater than the sum of the areas of squares a and b ?
"let length of each side of square a be 10 area of a = 10 ^ 2 = 100 since , length of each side of square a is increased by 100 percent to make square b length of each side of square b = 2 * 10 = 20 area of b = 20 ^ 2 = 400 since , length of the side of square b is increased by 25 percent to make square c length of each side of square c = 1.25 * 20 = 25 area of c = 25 ^ 2 = 625 difference in areas of c and cummulative areas of a and b = 625 - ( 400 + 100 ) = 225 percent is the area of square c greater than the sum of the areas of squares a and b = ( 225 / 500 ) * 100 % = 45 % answer d"
