For this question the answer is 2.5m (B)

You find this by: L=0.85m

W=0.4m

A rectangle had 4 sides (2 lengths and 2 widths)

So ...

To find 1 length and 1 Width you do 0.85+0.4=1.25m

Now you want to find the other 2 sides (L and W)

You can do: the same method and add it to 1.25m OR ...

You can do (I prefer this one) : (0.85+0.4) x2=?

This is the same as 0.85+0.4=1.25

1.25x2=2.5m
