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
[tex]Length= scale÷Actual = 5/36 = 5×36 = 180cm[/tex]
Width=scale÷Actual = 1/50 = 1×50 = 50cm
[tex]Width=scale÷Actual = 1/50 = 1×50 = 50cm[/tex]
Area of Rectangle = legnth × width
= 180cm × 50cm = 9000 cm2
[tex]= 180cm × 50cm = 9000 cm2[/tex]
Area of the electronic board is 9000 cm2
