Step-by-step explanation:
The figure shown has one pair of parallel sides and is a trapezium
The area (A) of a trapezium is calculated using
A = h(a + b)
where h is the height and a, b the length of the parallel sides
here h = 2w, a = w + 3 and b = 4w - 2, hence
A = × 2w(w + 3 + 4w - 2)
= w(5w + 1) = 5w² + w
Answer:
The scale for a model that is 30 inches long is 449.2 inches.
The scale for a model that is 2 feet long is 561.5 feet.
Step-by-step explanation:
Consider the provided information.
The USS Enterprise was 1,123 feet in length.
Part (A) What is the scale for a model that is 30 inches long?
1 feet = 12 inches.
First convert the length of USS enterprise in inches.
1×1,123 feet = 12×1,123 inches
1,123 feet = 13476 inches
Divide original length with the length of model.
The scale for the model is:
Hence, the scale for a model that is 30 inches long is 449.2 inches.
Part (B) What is the scale for a model that is 2 feet long?
Since, both the units are in feet, so simply divide original length with the length of model.
The scale for the model is:
Hence, the scale for a model that is 2 feet long is 561.5 feet.
