b)If the length of the triangle is x+3 then what is the base of the triangle?

**bobpursley**, Wednesday, March 4, 2009 at 2:03pma(5)=5^2+5*5+6

compute that.

Now, Area is also equal to 1/2 base*length

but when x=5, length is 8, and area is as above.

Area=1/2 (8)*base

solve for base.

A(5)=52+5(5)+6

5A=25+25+6

5A=56

A=56/5
