Given:

Length of a rectangular vegetable garden = 9 metres

Area of rectangular vegetable garden = 72 square meters

To find: perimeter of Elise's vegetable garden

Area of rectangular vegetable garden =
`72\,\,m^2`

Length × breadth = 72

9 × breadth = 72

breadth
`=(72)/(9)=8\,\,m`

Perimeter of rectangular vegetable garden = 2(Length + breadth)

=2(9+8)

=2(17)

=34 m
