o o 0.
6 E 2 I 1 / 2 +
6 FEET 2-1/2 INCH
1 1 E 5 I 1 / 4 +
17 FEET 7-3/4 INCH
1 8 • 2 5 I = 19 FEET 2 INCH
– 2 I 1 / 8 = 18 FEET 11-7/8 INCH
Multiplying Dimensions
What is the perimeter of a room with
three walls which measure 15 Feet
3-3/4 Inches each?
KEYSTROKE DISPLAY
3 x 1 5 E 3 I 3 / 4 =
45 FEET 11-1/4 INCH
Multiply 5 Feet 3 Inches by 11 Feet
6-1/2 Inches:
KEYSTROKE DISPLAY
5 E 3 I x 1 1 E
6 I 1 / 2 = 60.59375 SQ FEET
