Answer 1

A scale drawing for a rectangular parking lot measures 6.8 cm by 12.3 cm the scale is 5cm : 25cm

Find the area of the parking lot

Respuesta:

$On\ the\ Drawing\ the\ area\ is\ 83.64\ cm^{2}\\\\The\ real\ parking\ area\ is\ 2091\ cm^{2}$

Explicación paso a paso:

The scale is 5cm : 25 cm,

it means that each 5 cm in the draw, in the real lot is 25 cm

It means 1 cm in the draw is 5 cm in the real lot.

6.8 cm in draw is 6.8 x 5 = 34 cm in real lot

12.3 cm in draw is 12.3 x 5 = 61.5  cm in real lot

The real area is: 34 x 61.5 = 2091 cm^2

In the draw the area is:

6.8 cm x 12.3 cm = 83.64 cm^2
