What is a rectangle?
A rectangle is one of the types of quadrilaterals in which all four angles are right angles or equal to 90 degrees. It is four-sided polygon in which the opposite sides are parallel and equal to each other.
For the given situation,
The school garden is in the shape of the rectangle.
The school garden's length = 8.4 meters
The school garden's wide = 6.4 meters
The section used to grow lettuce, length = 2.2 meters
The section used to grow lettuce, width = 0.8 meters
Area of garden is not used to grow lettuce is
⇒ [tex][(8.4)(6.4)-(2.2)(0.8)][/tex]
⇒ [tex][53.76-1.76][/tex]
⇒ [tex]52[/tex]
Hence we can conclude that 52 square meters of garden is not used to grow lettuce.
