Question

In the given figure,ABCD is a square.Which of the following is the length of its side
​

Answer 1

Answer:

x=2

Step-by-step explanation:

18x-20=42-13x

18x+13x=42+20

31x=62

x=2

Answer 2

Given

• ABCD is a Square

To find

• Length of Side

we know that :

$\pink{ \boxed{ \sf{All \: Sides \: are \: equal \: in \: square}}}$

$\sf{Length \: o f \: AB=Length \: of \: BC}$

$\sf→18x - 20 = 42 - 13x$

$\sf→18x + 13x = 42 + 20$

$\sf→31x = 62$

$\sf→x = 2$

• Length of each Side = 2 units.
