A rancher has 1000m of fencing to enclose two rectangular corrals. The corrals have the same dimensions and one side in common. What dimensions will maximize the enclose area? ____________ |_____|_____| y . x THIS is all i've solved for so far my two formulas are 1) 1000=4x+3y 2) A=2LW two given that there are 2 rectangles. isolate the y in the first equation (1000-4x)/3 = y plug this equation into the 2nd function A=2x(1000-4x)/3 find derivative A = (2000x-8x^2)/3 A'= (2000-16x)/3 factor out 16 A'=16(125-x)/3 x=125m
