Problema Solution
The height of a triangle is 5 more than twice the length of the base. Find an expression for the area of the triangle.
Answer provided by our tutors
area of a triangle is given by:
(1/2)bh
where 'b' is the base and 'h' is the height
we are given:
h = b+5
therefore the area of the triangle may be expressed as:
(1/2)bh = (1/2)b(b+5) = (1/2)b^2 + (5b)/2
