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
