What is the height of a rectangle with a perimeter of 132.8mm and the base lenght of 60.2mm

Base=legnth

perimiter=width+width+height+height or

p=2legnth+2h

so if p=132.8

and base legnth=legnth=l=60.2 then

subsitute

132.8=2 (60.2) + 2h

132.8=120.4+2h

subtract 120.4 from both sides

12.4=2h

divide by 2

6.2=h

the height is 6.2mm
