Perimeter = 2(l+b)
36 = 2(l+b)/2
36 = l+b ----(1)
Now,
l = 4 + b
l-b = 4 ----(2)
adding (1) and (2)
l+b = 36
l - b = 4
2l = 40
l = 20m
putting l in (1)
20 + b = 36
b = 16m
36 = 2(l+b)/2
36 = l+b ----(1)
Now,
l = 4 + b
l-b = 4 ----(2)
adding (1) and (2)
l+b = 36
l - b = 4
2l = 40
l = 20m
putting l in (1)
20 + b = 36
b = 16m
