a numerical expression as given above, cannot have a perimeter. perimeter is the outer boundary of a geometrical body. therefore the question shoud have been wots the perimeter of a body having sides 2.5mm and 7.5mm. in that case it depends upon the shape of the figure, if its a rectangle, den 2(2.5+7.5)mm = 2(1)mm= 2mm.
Perimeter = 20mmGiven: Area = 25mmAssuming that the figure is a square:side:= square root of area= square root of 25mm= 5mmPerimeter:= 4 * sides= 4 * 5mm= 20mm
.7854 x 25mm x 25mm x 1000mm = 490,875 cubic mm converting to cc this is 490.875 cc (ml) formula: pi/4 x d2 x l = v
230mm x 110mm x 75mm.
The Occupational Health and Safety Act No 85 of 1993 states that in any office or workplace you must have the following in your first aid kit:Contents:-1 x Antiseptic Solution 100ml-1 x Roll Hypo-Allergenic Paper Tape-100 x Gauze Swabs 75mm x 75mm-10 x Plaster Strips Loose-10 x Sterile Gauze Swabs 75mm x 75mm (5's)-4 x First Aid Dressing No. 3-2 x Cottonwool 50g-4 x First Aid Dressing No. 5-1 x Forceps-2 x Green Plastic Interlocking Splints-1 x Scissors-2 x CPR Mouthpiece-10 x Safety Pins-2 x Pairs Gloves Medium-4 x Triangular Bandages-2 x Pairs Gloves Large-4 x Conforming Bandages 75mm-1 x Burn Dressing 10cm x 10cm-4 x Conforming Bandages 100mm-2 x Plaster Roll 25mm x 3, (Elastic Adhesive)
200mm
perimeter = 2h + 2b ....where h = height and b = base you say that the h = (2b+3) so 2h=2x(2b+3) so substitute that in and we have: perimeter = (2 x (2b +3)) + (2 x b) multiplying out gives perimeter = 4b + 6 + 2b = 6b+6 now we know the perimeter = 72mm = 6b+6 taking the 6 off both sides we get 6b=66mm divide by 6 and we find b=11mm we know h = 2b + 3 and that b=11 so h=22+3=25mm now Area of a rectangle = b x h = 11mm x 25mm = 275mm^2
About 3 1/4" x 3"
Metric micrometers are designed to 25mm range portions. They will be supplied in 0 to 25mm, 25 to 50mm, 50 to 75mm, etc. Tube or three-point micrometers come in smaller ranges though. Imperial micrometers come in 0 to 1in, 1 to 2in, 2 to 3in, etc.
It is about: 3 by 2.2 in inches
50mm x 24mm or 54mm x 25mm

You can't tell the perimeter from the area.Here are a few different rectangles and their perimeters.All of them enclose 12 square feet.1/2 x 24 .. . perimeter = 491 x 12 . . . . perimeter = 261.5 x 8 .. . . perimeter = 192 x 6 . . . . . perimeter = 162.4 x 5 .. . . perimeter = 14.83 x 4 . . . . . perimeter = 143.464 x 3.464 . . perimeter = 13.856
