Question 1046639: A square garden is to be enlarged to a rectangular by adding 5 ft. to the length and deducting 4 ft. from the width, with area unchanged. Determine present and new dimensions.

My partial attempt:
Area = length * width
Let s = side of square.
Square:
Length: s Width: s Area: s^2
Rectangle:
Length: s + 12 Width: s - 4 Area: (s + 5) (s - 4)

Question 1048321: The lower square base of the Washington Monument has a side 21 ft. more than the upper square base. Area of the lower base is 1869 sq. ft. more than the upper base. Determine dimensions of each square.
Area = length * width
Let x = lower base
Let y = upper base
Lower:
Side: x + 21 Side: x + 21 Area: (x + 21) (x + 21)
Upper:

Side: y Side: y Area: y^2
y^2 = (x + 21) (x + 21) + 1869
y^2 = x^2 + 21x + 21x + 441 + 1869
y^2 = x^2 + 42x + 2310
Unsure from here. Thanks.
