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

Serhud [2]

Answer:

i believe the answer would be y= -x-4

Step-by-step explanation:

a line that is perpendicular, will have and opposite reciprocal slope, so:

the slope of the line y=x-4 is 1, and the reciprocal of 1 is also 1.

now take the opposite of it, which is -1.

so the perpendicular line equation would be y=-x-4

i hope this helps :D

We went over this like 3 times. It sounds and looks like pure gibberish
kipiarov [429]

Answer:

3 pencils

Step-by-step explanation:

eraser= 0.25

pencil= 0.75

2(0.25)= cost of erasers

0.5 + p=2.75 (p=pencils)

-0.5         -0,5

p=2.25

divide 2.25 by 0.75
