Question

Find the value of x in the diagram

Answer 1

Key points :-

♧︎︎︎Diagram 2 is triple of Diagram 1

♧︎︎︎The area of Diagram 1 is 12cm² and area of diagram 2 is ×3 i.e. 36cm².

♧︎︎︎ The side of diagram 2 is also ×3 of diagram 1.

$\rule{300pt}{3pt}$

Since, The side is ×3

$\sf \: x \times 3 = 9 \\ \sf \: 3x = 9 \\ \boxed{ \tt \: x = 3}$

Therefore, The value of x is 3 in the diagram...
