<span>In two similar triangles, like the one we see above, the ratio of their areas is the square of the ratio of their sides. 

Based on the graph, we see that BD is 3 times larger than BA. This means that the area of DBE will be 3</span>² times larger, or 9 times larger, than the area of ABC.

Area of ABC = 3 square units
Area of DBE = 3 * 9 = 27 square units
Answer is A.

Tanya has a garden with a trench around it .The garden is a rectangle with length 2 1/2m and width 2 m.
Hunter-Best [27]

The area of the trench is  5 \frac{1}{2} m²

Step-by-step explanation:

Tanya has a garden with a trench around it

  • The garden is a rectangle with length 2 \frac{1}{2} m and width 2 m
  • The trench and garden together with length 3 \frac{1}{2} 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 \frac{1}{2} m and width 2 m

∴ Length = 2 \frac{1}{2} m

∴ Width = 2 m

Find the area of the garden

∴ A = 2 \frac{1}{2}  × 2 = 5 m²

∵ The trench and garden together with length 3 \frac{1}{2} m and width 3 m

∴ Length = 3 \frac{1}{2} m

∴ Width = 3 m

Find the area of the garden with the trench

∴ A = 3 \frac{1}{2}  × 3 = 10

The area of the trench = area of the garden with the trench - area of the garden

∴ The area of the trench = 10 \frac{1}{2}  - 5 = 5

The area of the trench is  5 \frac{1}{2} m²
