The difference of the areas of two squares is 375 square feet. Each side of the larger square is four times the length of a side of the smaller square. Find the length of a side of each square. x = side of small square 4x = side of large square To get the area of a square, just square one side. (4x)²  x² = 375 {difference of areas is 375} 16x²  x² = 375 {squared 4x} 15x² = 375 {combined like terms} x² = 25 {divided both sides by 15} x = 5 {took square root of both sides} 4x = 20 {substituted 5, in for x, into 4x} each side of small square is 5 ft each side of large square is 20ft © Algebra House
