Answer:

1 ft²

Step-by-step explanation:

The scale factor = 1 : 20

<u>The area is the product of two dimensions, so the area of the model part to actual part is:</u>

1 ² : 20 ² =
1 : 400

<u>If the actual plane has wing area of 400 ft², then the model will have wing area:</u>

400 ft² / 400 = 1 ft²

Can someone help me and show how to write the perimeter equation to find x.

Answer:

a) 10x + 8 = 21

b) x = 1.3

Step-by-step explanation:

The line of symmetry is a vertical line that passes through point C.

That makes sides BC and CD congruent, and sides AB and ED congruent.

perimeter = AB + BC + CD + DE + EA

perimeter = 2x + 3 + x + 1 + x + 1 + 2x + 3 + 4x = 10x + 8

perimeter = 21

a) Equation:

10x + 8 = 21

10x = 13

x = 1.3
