on a scale drawing of the front of a square each side of the of the earring is 3.2 the scale from the earring to th drawing is 4mm to 2 cm what is the area of the actual earring?
To find the area of the actual earring, we need to determine the length of each side in centimeters, and then square that value.
According to the scale, 4mm represents 2cm.
If each side of the earring on the scale drawing is 3.2, we can determine the length of each side in centimeters by multiplying it by the scale factor:
3.2 * 2cm/4mm = 3.2 * (2/0.4) = 3.2 * 5 = 16 cm
Therefore, each side of the actual earring is 16 cm.
To find the area, we square this value:
Area = Length * Width = 16cm * 16cm = 256 cm^2
So, the area of the actual earring is 256 square centimeters.
ok the answers are 6.4mm 20.48mm 12.8mm and 40.96mm witch one
We can calculate the actual length of each side of the earring by using the scale factor.
According to the scale, 4mm represents 2cm.
So, we can determine the actual length of each side by multiplying the length on the scale drawing by the scale factor:
Actual length = 3.2cm * (4mm/2cm)
Actual length = 3.2cm * 2
Actual length = 6.4mm
Therefore, the actual length of each side of the earring is 6.4mm.
To find the area of the earring, we square the length:
Area = (6.4mm)^2 = 40.96mm^2
So, the correct answer is 40.96mm^2.
nice!😃 the scale from a square park to a drawing of th park is 5 m to 1cm the real park has an area of 1600 m what the area of the drawing of the park
To find the area of the drawing of the park, we need to determine the scale factor and then use it to convert the actual area of the park to the area on the drawing.
According to the scale, 5m represents 1cm.
To find the scale factor, we can convert the units:
5m = 500cm
Therefore, the scale factor is 500cm to 1cm.
To find the area on the drawing, we need to square the scale factor:
Scale factor = (500cm/1cm)^2 = 250,000
Now, we can determine the area of the drawing by multiplying the scale factor by the actual area of the park:
Area of the drawing = Scale factor * Actual area
Area of the drawing = 250,000 * 1600m^2
Calculating this gives us:
Area of the drawing = 400,000,000 cm^2
So, the area of the drawing of the park is 400,000,000 square centimeters.
simpler
Apologies for the confusion. Let's simplify the calculation.
The scale from the park to the drawing is 5m to 1cm.
To find the area of the drawing, we need to square the scale factor, which is the ratio of the lengths.
The ratio of lengths is 5m/1cm. To simplify the units, we convert 5m to cm: 5m = 500cm.
So, the scale factor is (500cm/1cm)^2 = 250,000.
To find the area of the drawing, we multiply the actual area of the park by the scale factor:
Area of the drawing = 1600m^2 * 250,000 = 400,000,000 cm^2.
Therefore, the area of the drawing of the park is 400,000,000 square centimeters.
