Answer:

AD=2

Step-by-step explanation:

$\frac{6}{12} =\frac{AB}{20} \\AB=\frac{6}{12} \times 20=10\\AD+DF+FB=10\\AD+6+FB=10\\AD+FB=10-6=4\\AD+AD=4 ( \because ~FB=AD )\\2AD=4\\AD=4/2=2$

Answer:

AB=16

BC=15

AC=12

PQ=12

QR=12

PR=19

Step-by-step explanation:

well you know that the perimeter is the sum of all sides

so we have

$(2x)+(2x+4)+(2x+3)=(2x)+(2x)+(3x+1)\\\\2x+2x+4+2x+3=2x+2x+3x+1\\\\(2x+2x+2x)+(4+3)=(2x+2x+3x)+(1)\\\\6x+7=7x+1\\\\6x+7-1=7x\\\\6x+6=7x\\\\6=7x-6x\\\\x=6$

so the sides are:

$AB=2x+4=2(6)+4=12+4=16\\\\AB=16$

$BC=2x+3=2x+4-1=16-1=15\\\\BC=15$

$AC=2x=2(6)=12\\\\AC=12$

$PQ=2x=12\\\\PQ=12$

$QR=2x=12\\\\QR=12$

$PR=3x+1=3(6)+1=18+1=19\\\\PR=19$

So there you are.
