so say we only know the width
which is 10
and the perimeter which is 30
hint( perimeter is all of the sides added up
anyways so we know that theres 2 sides that are ten so that gives us
30 - 20 = 10
but there are 2 more sides to lets divide by 2
10 ÷ 2 = 5
so the length would be 5
heres the equation
P = perimeter
W = width
L = length
s
P - 2w = L ÷ 2
:P hope this helps
