Answer:

48 ft²

Step-by-step explanation:

The area of the green shaded part will be :

Area of the entire rectangle green shape assumed complete minus the area of the removed parts{ small rectangle + triangle }

Area of the entire rectangle green shape assumed complete

Area= length * width

A= l*w

A= 5ft * 12 ft = 60 ft²

Area of small rectangle removed part

2 * 3 = 6 ft²

Area of the triangle removed

A= 1/2 * b * h

A= 1/2 * 3 * 4

A= 6 ft²

Area of the outdoor carpet needed for the hole

60-{6+6}

60 -12 = 48 ft²

The ratio of bleach to water in a cleaning solution is 2:18. For every 1 liter of bleach, how many liters of water are in the so

Paha777 [63]

Answer:

For every 1 liter of bleach there are 9 liters of water in the solution

Step-by-step explanation:

∵ The ratio of bleach to water in a cleaning solution is 2 : 18

- That means for every 2 liters of bleach there is 18 liters of water

∵ There is 1 liter of bleach

- Let us use the ratio method

→ bleach : water

→ 2 : 18

→ 1 : x

- By using cross multiplication

∴ x × 2 = 1 × 18

∴ 2 x = 18

- Divide both sides by 2

∴ x = 9

∵ x represents the number of liters of the water in the solution

∴ The number of liters of the water in the solution is 9

For every 1 liter of bleach there are 9 liters of water in the solution
