<h3>Given</h3>
- room height is x feet
- room length is 3x feet
- room width is 3x feet
- a door 3 ft wide by 7 ft tall
<h3>Find</h3>
- The net area of the wall, excluding the door
<h3>Solution</h3>
The area of the wall, including the door, is the room perimeter multiplied by the height of the room. The room perimeter is the sum of the lengths of the four walls.
... gross wall area = (3x +3x +3x +3x)·x = 12x²
The area of the door is the product of its height and width.
... door area = (7 t)×(3 ft) = 21 ft²
Then the net wall area, exclusive of the door is ...
... net wall area = gross wall area - door area
... net wall area = 12x² -21 . . . . square feet
Answer:
12.5cm
Step-by-step explanation:
Each side of the pentagonal garden has a length of 2.5 cm.
A pentagon has 5 sides.
Since the garden has congruent sides, all its lengths are equal.
Therefore:
Distance Walked by Tanya
= 5 X 2.5
=12.5cm

Answer:
Shirt-$19
Cap-$24
Step-by-step explanation:
5s+1c=119
1s+1c=43
1c=43-1s
substitute:
5s+(43-1s)=119
5s+43-1s=119
4s=119-43
4s=76
1s=19
substitute:
1c=43-(19)
1c=24
