The area of the trench is 5
m²
Step-by-step explanation:
Tanya has a garden with a trench around it
- The garden is a rectangle with length 2
m and width 2 m - The trench and garden together with length 3
m and width 3 m
We need to find the area of the trench
The area of the trench is the difference between the area of the garden with the trench and the area of the garden
The formula of the area of a rectangle is A = length × width
∵ The garden is a rectangle with length 2
m and width 2 m
∴ Length = 2
m
∴ Width = 2 m
Find the area of the garden
∴ A = 2
× 2 = 5 m²
∵ The trench and garden together with length 3
m and width 3 m
∴ Length = 3
m
∴ Width = 3 m
Find the area of the garden with the trench
∴ A = 3
× 3 = 10
The area of the trench = area of the garden with the trench - area of the garden
∴ The area of the trench = 10
- 5 = 5
The area of the trench is 5
m²

Use this formula, it’s called distance formula
One way is to find common factors
example
8/6=4/3 because 8/6, 8 and 6 have common factor of 2 so divide that out to get 4/3
basically divide the LCM from each
so factor
we can combine 36m-48m into -12m
we have
-12m/6m
common factor is 6m
-12m/6m=(-2)/1 times (6m)/(6m)=-2 times 1=-2
answer is -2
