modular_modexp_compute_v1_601307018_3621
A rectangular garden with area $684$ square meters is to be designed with integer side lengths. The landscaper chooses dimensions that minimize the difference between length and width; let $a$ be this minimal difference. Separately, a solar panel array of area $49284$ square meters is planned with integer dimensions th...
