The length of a rectangle is three times its width. The perimeter of the rectangle is 24 cm.
Calculate the area of the rectangle.

its 50 miles away from the starting point

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:

answer is b
