The perimeter of the rectangle is equal to the perimeter of the square. What is the longest side length of rectangle?
A) 7 units
B) 4 units
C) 6 units
D) 10 units

Step-by-step explanation:

5x-3=3x+1

or, 5x-3x=1+3

or, 2x=4

or, X = 4÷2

or, X = 2

4x+2

4*2+2

= 1o

the ans is 10 units

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
