Step-by-step explanation:

Area = 30 x 15 - 10 x 5

Area = 450 - 50

Area = 400 m^2

Hope that helps! :)

400 m^2

Step-by-step explanation:

the figure is composed by a square and a rectangle

Area of the square = side^2 = 10^2 = 100 m^2

area of the rectangle = base x height = 20 x 15 = 300 m^2

total area = 300 + 100 = 400m^2

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

y=-2x+1500
