Question 1051074
b for base
y for height
area restriction, 120 sq.ft. maximum


{{{(1/2)by<=120}}}


GIVEN:  {{{b=16*feet}}}.


{{{16y/2<=120}}}


{{{8y<=120}}}


{{{y<=120/8}}}


{{{y<=(2*5*2*2*3)/(2*2*2)}}}


{{{y<=15}}}


The more practical answer is  {{{0<y<=15}}}.  No "dimension" of a triangle can be negative.
