The length is 20 m, the width is 10 m, and the area is 200 m.

Step-by-step explanation:

Here is why, since the length is 16 cm we first divide by 4 then multiply by 5. When we divide by 4 we get 4 and when we multiply by 5 to get 20. Then, we do the same for the width to get 10. Lastly, we just multiply both together.

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8

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:
