Question

Scale drawing of the electronics board

Answer 1

Area of the electronic board is 9000 cm2

Step-by-step explanation:

Write ratios to represent the unknown actual length and width of the display to the scale length and width of the display.

The Electronic board always seems like a rectangular shape

Length= scale÷Actual = 5/36 = 5×36 = 180cm

$Length= scale÷Actual = 5/36 = 5×36 = 180cm$

Width=scale÷Actual = 1/50 = 1×50 = 50cm

$Width=scale÷Actual = 1/50 = 1×50 = 50cm$

Area of Rectangle = legnth × width

                         = 180cm × 50cm = 9000 cm2

$= 180cm × 50cm = 9000 cm2$

Area of the electronic board is 9000 cm2
