Question

Please give me answer​

Answer 1

Answer:

PERIMETER OF AQUADRILATERAL =SUM OF ITS ALL SIDES.

Step-by-step explanation:

sides are x-3,x+4,x,x+6.

so now add all 4 sides

x-3+x+4+x+x+6=31

4x+7=31

4x=24

x=6

the sides will be x-3=6-3=3

x+4=6+4=10

x=6

x+6=6+6=12

verification 3+10+6+12

=31

Answer 2

Step-by-step explanation:

AB = X-3

BC = X+4

CD = X+6

DA = X

Perimeter = AB + BC + CD + DA

31cm =[X- 3] + [X + 4] +[X+6] +X

31 = X + 3 + X + 4 + X + 6 + X

31 = 4X + 13

31 -13 = 4X

X. = 18÷4

X. = 4.5
