Question

what is the area of these polygon plz answer me

Answer 1

Answer:

b=770

c=300

Step-by-step explanation:

For part b, i would break it down into two triangles and a rectangle.

triangle (35*10)/2=175

rectangle=12*35=420

Total area=2*triangles+1 rectangle= 2*175+420=770

For part c, i would use two triangles

(12*20)/2=120

(30-12)=18     (18*20)/2=180

Total area= triangle + triangle= 120+180=300
