$A=\frac{1}{2}ap$ where a is the apothem and p is the perimeter. Perimeter is simple: just count the number of sides the polygon has and multiply it by 3 (the length of one side).

p = 3(9) is 27 inches for the perimeter.

We have what we need now to find the area:

$A=\frac{1}{2}(4.1)(27)$ and

$A=\frac{1}{2}( 110.7)$ so

A = 55.35 square inches

Each sister bought a gift for their mom. Maggie spent 3 times as much as Karen. Karen spent half as much as Jasmine. Altogether,

snow_tiger [21]

Answer:

Maggie spent =30

Karen spent = 10

Jasmine spent =20

Step-by-step explanation:

In this we use algebra to solve.we give the sisters unknowns, to help us solve the equation.

we dont know how much jasmine used so we give her the unknown x.you can use any letter but ill us x.

karen used half as much as karen so we give her 1/2x because it was half of jasmine.maggie used 3 times that of karen so w give her 3(1/2x).

maggie =3(1/2x)

Karen =1/2x

jasmine =x

3(1/2x) + 1/2x + x = 60

3/2x + 1/2x + x = 60

2x + x = 60

3x=60

x=20

where we have x =we replace with 20

e.g karen 1/2x => 1/2 x 20 =10

if you need any clarifications please do tell me in the comment section.i would like to help more if you need help.thx

Hope this helps and if it does mark as branliest anwer thx
