Step-by-step explanation:
84 sq. ft of the wall has to be covered with paint or wallpaper.
Step-by-step explanation:
- Step 1: Find the area of wallpaper to be covered by calculating the area of the wall and subtracting the areas of the window, mirror and fireplace from it. All are rectangular in shape with are given by A = length × width
Area of the wall = 8 × 16 = 128 ft²
Area of the window = 18/12 × 14 = 1.5 × 14 = 21 ft² (since 1 ft = 12 in)
Area of the fireplace = 5 × 3 = 15 ft²
Area of the mirror = 4 × 2 = 8 ft²
- Step 2: Calculate the area to be painted or covered with wallpaper
Area of the wall to be covered with paint or wallpaper = 128 - (21 + 15 + 8)
= 128 - 44
= 84 ft²
The exhibition of 7 birds will cost $2,450
<h3>
How to calculate the total cost ?</h3>
The wildlife center charges a basic fee of $325 for a bird exhibition
When 5 birds were exhibited, $125 additional fee was charged
The additional fee for a bird is
= 125/5
= 25
Therefore the total cost of exhibiting 7 birds can be calculated as follows
= 325 + 25
= 350
350 × 7
= 2,450
Hence the total cost for the exhibition of 7 birds is $2,450
