Okay, so let's take all the measurements we have to sum up ⇨ 27.5, 2.75, 275 cm.
We've to find the sum. So we need to add these measurements ⇨ 27.5 + 2.75 + 275 cm
Now, let's solve it.
[tex] \tt \: 27.5 + 2.75 + 275 \\ \\\tt \: Add \: 27.5 \: and \: 2.75 \: to \: get \: 30.25. \\ \\\tt \:30.25+275 \\ \\ \tt \:Add \: 30.25 \: and \: 275 \: to \: get \: 305.25. \\ \\ = \boxed{\boxed{\bf \: 305.25 \: cm}}[/tex]
Hey there!
To find the sum of the measurements means to add all the measurements together.
So, 27.5 cm + 2.75 cm + 275 cm = ?
27.5 cm + 2.75 cm + 275 cm
= 30.25 cm + 275 cm
= 305.25 cm
Hope it helps ya!
