Most of this is translating description into numeric symbols and relationships.

x = length
y = breadth
A = area using x and y
.
, and , and conclude here that

Condition of and , the dimension size increase:

Remember that we understood from given, .

This set of equations lets you solve for either A or y:
and

WHAT NOW TO DO:
Solve each of those for A, and then equate the formulas. Solve for y. Use the value to solve for x.
