Question

Which equation would best help solve the following problem?
The height of a triangle is 6 m more than its base. The area of the triangle is 56 m2. Find the length of the base.

a. 56=1/2(x)(x+6)
b. 56=1/2(x2+6)
c. 56=x(x+6)
d. 56=x2+6

Answer 1

area = 1/2 x base x perp. height
56 = 1/2x (base)x (base + 6)
so a.
