Step-by-step explanation:
GIVEN: The length of each side of a square is inches more than the length of each side of a small square. The sum of the areas of the square is
inches.
TO FIND: the lengths of the sides of the two squares.
SOLUTION:
let the length of side of small square be
Area of small square
As length of each side of bigger square is more than the smaller square
length of side of bigger square
Area of bigger square
Also
Sum of areas of both square
as the length of side can never be negative
length of side of smaller square
length of side of bigger square
Hence the length of smaller and bigger square are and
respectively.
3x - 4(4) = 65
First, simplify 4 × 4 to get 16. / Your problem should look like: 3x - 16 = 65
Second, add 16 to both sides. / Your problem should look like: 3x = 65 + 16
Third, simplify 65 + 16 to 81. / Your problem should look like: 3x = 81
Fourth, divide both sides by 3. / Your problem should look like: x =
Fifth, simplify to 27. / Your problem should look like: x = 27
Answer: x = 27
First, simplify 4 × 4 to get 16. / Your problem should look like: 3x - 16 = 65
Second, add 16 to both sides. / Your problem should look like: 3x = 65 + 16
Third, simplify 65 + 16 to 81. / Your problem should look like: 3x = 81
Fourth, divide both sides by 3. / Your problem should look like: x =
Fifth, simplify
Answer: x = 27
