Question

The side of a square exceeds the side of
another square by 5 cm. The difference
of their areas is 325 sq. cm. Find the sides of
each square.

Answer 1

Answer:

Step-by-step explanation:

let the side of the square is x

the another side of the square is x + 5

the difference of the areas = x² + x² + 25 +5x

                                    325 - 25 = 2x² + 5x

                                     2x²+5x - 300 = 0

                                     2x² + 20x-15x-300 = 0

                                     2x(x+20) - 15(x+20) = 0

                                     x =15/2 and x = -20

so another side is 15/2 + 5

                           = 25/2

side of each square is 15/2 and 25/2
