Find the area of the polygon.
look at the picture
a : 24.6 square units
b : 25.8 square units
c: 26.3 square units
d: 27.5 square units

option D: 27.5 square units

Step-by-step explanation:

Divide the polygon in 6 figures

see the attached figure

Area of figure 1 (right triangle)

A1=(1/2)(3)(3)=4.5 units²

Area of figure 2 (rectangle)

A2=(1)(3)=3 units²

Area of figure 3 (rectangle)

A3=(1)(3)=3 units²

Area of figure 4 (right triangle)

A4=(1/2)(3)(3)=4.5 units²

Area of figure 5 (right triangle)

A5=(1/2)(4)(5)=10 units²

Area of figure 6 (right triangle)

A6=(1/2)(1)(5)=2.5 units²

The total area is equal to

At=A1+A2+A3+A4+A5+A6

At=4.5+3+3+4.5+10+2.5=27.5 units²

Option D.

Step-by-step explanation:

As we know area of a triangle =

1. Area of ΔJKL =

=

=7.5 square units

2. Area of ΔIJL =

=  

= 7.5 square units

3. Area of triangle IKL =

=

= square units

Now area of ΔJKL + ΔIJL + ΔIKL = 7.5 + 7.5 + 12.5

= 27.5 square units

Option D. is the answer.

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
