Step-by-step explanation:
<span>The dimension of the rectangle would be length=#4/sqrt3# and width =4-#4/3= 8/3#
Explanation:
Let one vertex on the x axis be x, then the other vertex would be -x. Length of the rectangle would be thus 2x and width would be #4-x^2#
Area of the rectangle would be A=#2x(4-x^2)= 8x-2x^3#
For maximum area #(dA)/dx=0=8-6x^2#, which gives x=#2/sqrt3#
The dimension of the rectangle would be length=#4/sqrt3# and width =4-#4/3= 8/3#
