Using scale concepts, it is found that the length of her office is of 10 ft, while the width is of 5 ft.
------------------------
- The scale of 6 cm to 15 ft means that each <u>6 cm in the drawing represent 15 ft in actual dimensions</u>.
- From this, a rule of three is applied to find the dimensions.
First, we find the actual length:
6 cm - 15 ft
4 cm - x ft
The actual length is of 10 ft.
Then, we find the actual width:
6 cm - 15 ft
2 cm - x ft
The actual width is of 5 ft.

They all use the metric unit to measure things (e.g. inches, centimeters, etc.)
As far as I know, I think the difference might be that a yardstick only measures 1 yard. It has 36 inches (which is 3 feet, which is also 1 yard).
A ruler usually is only 12 inches.
A measuring tape is usually 12 feet.
That's what I know.
Answer:
The lateral area of this square pyramid is 100 in^2
Step-by-step explanation:
The lateral area of a polyhedron is the added area of all lateral faces (faces on the side) excluding the bases.
In this case, the lateral sides of the square pyramid are the 4 triangular faces on the sides.
AREA OF ONE TRIANGULAR FACE (given by the formula 1/2 x bh):
1/2 x 10 x 5 = 25
Multiply that by 4 since all 4 triangular faces are similar:
25 x 4 = 100
So the lateral area of the square pyramid is 100 in^2.
