Question

A toy company is building dollhouse furniture. A scale drawing of a rectangular door of a dollhouse has a height of 5 centimeters and a width of 3 centimeters. What is the perimeter of the actual door of the dollhouse using the scale 2:8?
4 cm
10 cm
16 cm
64 cm

Answer 1

Answer:

The perimeter of actual door is 64 cm.

Explanation:

Scale perimeter of door:

• 2(Length + Width)

• 2(5 + 3)

• 2(8)

• 16

-----------

$\sf \dfrac{actual \ length}{scale \ length} = \dfrac{actual \ ratio}{scale \ ratio}$

-----------

$\sf \dfrac{actual\:length}{16} = \dfrac{8}{2}$

$\sf {actual\:length} = \dfrac{16(8)}{2}$

$\sf {actual\:length} =64$
