If you could explain to me how you get the answer, that will be great!

130.4

Step-by-step explanation:

find the area of the rectangles

5(8)=40

5(8)=40

4(8)=32

find the area of both of the triangles

formula: 2(bh÷2)

substitute: 2(4 x 4.6 ÷ 2)

solve

2(9.2)

18.4

add all of the areas

40+40+32+18.4=130.4

126

Step-by-step explanation:

From the statement , we have been given given

blue jays : black crows : red robins : cardinal

That is :

59 : 68 : 12 : 1

Total ratio = 59 + 68 + 12 + 1 = 140

Therefore : the number of blue jays if 300 visit is :

ratio of blue jay / total ratio x 300

That is

59/140 x 300

= 126. 4285714

≈ 126
