lets the height of the triangle h, and the base is b

first sentence means h = 1 + 2b

Area of the triangle formula is

A = 1/2(b*h)

since h = 1 + 2b

then A = 1/2 [ b * (1+2b)]

then you just need to replace the A with the given number and solve for b. After you find b, substitute b into h = 1+ 2b to find h

good luck
