What is the answer to this?
amm1812

Answer:

<h2>40.1 cm</h2>

solution,

BC=8.4 cm

AB=12 cm

BD=4.1 cm

We have to find out: AC ,CD

using Pythagoras theorem:

In ∆ABC ,<B=90°

{(ac)}^{2}  =  {(ab)}^{2}  +  {(bc)}^{2} \\  {(ac)}^{2}   =  {(12)}^{2}  +  {(8.4)}^{2}  \\  {(ac)}^{2}  = 144 + 70.56 \\  {(ac)}^{2}  = 214.56 \\ ac =  \sqrt{214.56}  \\ ac = 14.64 \: cm

Similarly,

In ∆BCD, CB=90

cd =   \sqrt{ {(8.4)}^{2} +  {(4.1)}^{2}  }

=  \sqrt{70.56 + 16.81}  \\  =  \sqrt{87.37}  \\  = 9.34 \: cm

Perimeter:

AC+CD+AD

=14.64+9.34+(12+4.1)

=40.08

= 40.1 cm

Hope this helps...

Good luck on your assignment..
