Question

Bailey writes the expression g2 + 14g + 40 to represent the area of a planned school garden in square feet. If g = 5, what are the dimensions of the school garden? 20 feet by 2 feet 10 feet by 4 feet 12 feet by 7 feet 15 feet by 9 feet

Answer 1

if g=5
then g*g+14g+40
=5*5+14*5+40
=25+70+40
=135
so area of garden is 135sqfeet
here is no extra info given so,
school garden must be of a rectangle shape
so area of rectangle is l*b
now according to solved pro.
l*b = 135
now the only pair of l and b having multiplication 135 is option 4 i.e.
15feet by 9feet
so the ans is option no. 4
