Question

a rectangular garden has one side length of a and another length of a + 2. find the perimeter of the garden?​

Answer 1

$\large \underline{\sf{given : }}$

$\pink{ \sf{length = ( \: a \:) \: m }} \\ \pink{ \sf{breadth = (a + 2) \: m}}$

$\large \underline{\sf{ to \: find : }}$

$\green{ \sf{perimeter \: of \: rectangular \: garden}}$

$\large \underline{\sf{solution: }}$

$\blue{ \sf{perimeter \: of \: rectangular \: garden = 2(l + b)}} \\ \blue{ \sf{ = 2(a + a + 2) \: m}} \\ \blue{ \sf{ = 2(2a + 2) \: m}} \\ \blue{ \sf{ = (4a + 4) \: m}}$

$\boxed{ \red{ \sf{perimeter \: of \: garden = (4a + 4)m}}}$
