Answer 2

Whenever you get a chance, can you upload the image?

Answer 3

@SaranyaMahes is this what you're referring to?

Answer 4

The length is \(1030\) millimeters for each of these 3 boards, so the total length is:\[3\times1030=3090\text{ millimeters}\]

Answer 5

(Sorry, you might have to click on the pictures to see the whole thing.)
To get the total length of these two boards, each being 950 millimeters:\[2\times950=1,900\text{ millimeters}\]

Answer 6

Now you add these two length values together since we don't need the width:\[3090+1900=4990\]But this is in millimeters! You're asked to answer in meters.

To get meters from millimeters, this is the equation: If \(a\) is your length in millimeters, and \(b\) is your length in meters\[\color{crimson}{a}\times10^{-3}=b\]We know \(a\) to be \(4990\), so now we need to convert that using the equation.\[\color{crimson}{4990}\times10^{-3}=4.99\]What does \(4.99\) round up to?
