a rectangular yard is 25 ft by 19 ft. the yard is covered with grass except for a
9.5-ft square flower garden. how much grass is in the yard?

Step-by-step explanation:

we know that

To find out how much grass is in the yard subtract the area of the flower garden from the total area of the rectangular yard

so

Find out the area of the rectangular yard

Find out the area of the square flower garden

so

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
