Atriangular poster has a base of 2 1/2 feet and a height of 1 3/4 feet what is the area of the poster

a=

Step-by-step explanation:

formulas:

a= b x h x

or           (both equations get the same answers)

a= b x h ÷ 2

imma stick with the second one kuz i usually use that one but ur preference.

so,

base(b) = =

height(h) = =

now fill it in to the equation:

a=b x h x                        a= b x h ÷ 2

a= x x                         a= x ÷ 2

a=                                   a= ÷ 2

a=                                   a= ÷ 2

                                          a=  

                                           a=

o well i did both lol

now you ca compare the two equations now  :]

plz give brainliesttttt

i dont know

step-by-step explanation:

so, converting firstly the mixed fractions to improper fractions and then "adding".
