Re: measure distance of diag. of monitor to nearest 1/10 cm

If that rule is ap...

Re: find the perimeter of a bird house 2 ft 7in. by 1ft 5 in.

Feet: (2 + 1) + (2 + 1) = 3 + (2 + 1) = 3 + 3 = 6

Inches: (7 + 5) + (7 + 5) = 12 + (7 + 5) = 12 + 12 = 24

So, 24 inches converts to 2 feet

Add Feet: 6' + 2' = 8 feet
