Scale drawing of the electronics board
lora16 [44]

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

Explain how to find the area of a square if you only know the length of one side is 23 feet? (APAP) 99 POINTS TOO
tatiyna

Answer:

529 feet squared

Step-by-step explanation:

We know that the sides of a square are all the same length, and the formula to find the area of a square is length time width, so to find the area of the square we multiply 23 by 23, or square 23. 23 times 23 equals to 529 so the area of the square is 529 feet squared.
