Answer 2

Given:

36 unit squares are joined to form a rectangle.

To Find:

find the perimeter of rectangle.

Solution:

so, of rectangle is 36 units 

by using trail and error method the possibilities to get the area36 units:

$: ⟹ 6 \times 6 = 36 \\ \\ : ⟹4 \times 9 = 36$

as it's a rectangle the length and breadth differ so, let's go with the second option

$\sf \blue{length : 9cm} \\ \sf \ \pink{breadth : 4cm}$

$\sf {\red{ \underbrace{perimeter = 2 ( l + b)}}}$

$\sf : ⟹ \: perimeter = 2(4 + 9) \\ \\ \sf : ⟹ \: perimeter =2 \times 15 \: \: \\ \\ \sf : ⟹ \: perimeter =30cm \: \: \:$

hope this helps.!!
