Alexeev081 [22]

Answer:

The largest rectangular space is $24m^{2}$

Step-by-step explanation:

Given a 20m long wire fence, implies that the perimeter of the fence has been given, because Perimeter can be defined as the length of the boundary of a figure (in this case, a rectangle)

So, from the formula: Perimeter = 2 (L + B) = $20m^{2}$

We have that L + B = $10m^{2}$

The possible values of L and B are:

(L, B) = (9, 1), (8, 2), (7, 3) and (6, 4).

The areas of the rectangle that will be formed using these values are respectively; $9m^{2}$ , $16m^{2}$ , $21m^{2}$ and $24m^{2}$ , the largest area of which is the last which corresponds to the values (6, 4).
