Question

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

Answer 1

Answer:

a=$2\frac{3}{16}$

Step-by-step explanation:

formulas:

a= b x h x $\frac{1}{2}$

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) = $2\frac{1}{2}$ = $\frac{5}{2}$

height(h) = $1\frac{3}{4}$ = $\frac{7}{4}$

now fill it in to the equation:

a=b x h x $\frac{1}{2}$                        a= b x h ÷ 2

a=$\frac{5}{2}$ x $\frac{7}{4}$ x $\frac{1}{2}$                         a=$\frac{5}{2}$ x $\frac{7}{4}$ ÷ 2

a=$\frac{35}{16}$                                   a=$\frac{35}{16}$ ÷ 2

a=$2\frac{3}{16}$                                   a=$\frac{35}{8}$ ÷ 2

                                          a=$\frac{35}{16}$  

                                           a=$2\frac{3}{16}$

o well i did both lol

now you ca compare the two equations now  :]

plz give brainliesttttt
