If the dimension of the garden is 2.5 m x 2 m and the dimension of the garden+trench is 3.5 m x 3 m, then the area of just the trench is 5.5 m².

Step-by-step explanation:

The dimensions of the garden that Tanya has:

Length = 2 ½ m = 2.5 m

Breadth or width = 2 m

The area of the rectangular garden = length * breadth = 2.5 × 2 = 5 m²

The dimensions of the trench and garden together:

Length = 3 ½ m = 3.5 m

Breadth or width = 3 m

The area of the trench and garden together = length × breadth = 3.5 × 3 = 10.5 m²

Thus,  

The area of just the trench is given by,

= [area of the trench and garden together] – [area of the rectangular garden]

= 10.5 m² – 5  m²

= 5.5 m²

Answer:

5.5

Step-by-step explanation:

The dimensions of the garden that Tanya has:

Length = 2 ½ m = 2.5 m

Breadth or width = 2 m

∴ The area of the rectangular garden = length * breadth = 2.5 × 2 = 5 m²

The dimensions of the trench and garden together:

Length = 3 ½ m = 3.5 m

Breadth or width = 3 m

∴ The area of the trench and garden together = length × breadth = 3.5 × 3 = 10.5 m²

Thus,  

The area of just the trench is given by,

= [area of the trench and garden together] – [area of the rectangular garden]

= 10.5 m² – 5  m²

= 5.5 m²
