If a rectangle has a perameter of 52cm and width of 12cm what is the length?
Perimeter of a rectangle = 2 x length + 2 x width. 52 = 2l + 2 x 12 = 2l + 24 (Where l is the length) 2l = 52 - 24 = 28 length = 28/2 = 14 cm
How do you find the length and width of rectangle when given the perimeter but not the width or length?
by appying 2l+2w
A rectangle has a perimeter of 52 cm and a width of 12 cm What is the length?
P=2(w)+2(l) 52=2(12)+2(l) 52=24+2l 52-24=2l 28=2l 14=l The length is 14 cm.
