9.) express the area of this triangle as a polynomial. (remember a=1/2b h

Plug in the values for b =   and h = 

A = 
Simplify.... 
A = 

Base is the long bottom part
hiehg is the vertical bit

remember:

add exponnets when multiplying by similar base
and
(ab)(cd)=(a)(b)(c)(d)=(ac)(bd), associative

given
base=4ab²c⁷
height=3a²b⁵

A=(1/2)(4a¹b²c⁷)(3a²b⁵)
A=(2)(a¹)(b²)(c⁷)(3)(a²)(b⁵)
A=(2)(3)(a¹)(a²)(b²)(b⁵)(c⁷)
A=(6)(a³)(b⁷)(c⁷)
A=6a³b⁷c⁷
