Answer:
6.75
Step-by-step explanation:
The shaded area amounts to two congruent equilateral triangles. Each has a side length of 2(1 in)cos(30°) = √3 in.
The height of an equilateral triangle with side length √3 is ...
height = (√3 in)sin(60°) = 3/2 in
Then the area of the two equilateral triangles is ...
A = bh = (√3 in)(3/2 in) = 3√3/2 in^2
The square of the numerical value of the area is ...
A^2 = ((3/2)(√3))^2 = 27/4 = 6.75
The square of the shaded area is 6.75.
Essentially, you must multiply 22 by 400. You get 8800 km apart for your answer.
Answer: 1 : 150
Step-by-step explanation:
The length of the model is 36cm. The length of the real aeroplane is 54 cm. This length seems implausible as it is of the real plane so I will assume that you meant to type 54m.
First convert 54 m to centimetres:
1 m = 100cm
= 54 * 100
= 5,400 cm
Length of model : length of plane
36 : 5,400
Divide both sides by 36:
= 1 : 150
