I need help on Area plz

139 cm squared

Step-by-step explanation:

First separate it:

10x3

7x7

4x15

These are the 3 rectangles that make up this shape

Then multiply

10x3=30

7x7=49

4x15=60

Then add your answers

30+49+60=139cm squared

99

step-by-step explanation:

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
