$\frac{1}{11}+\frac{1}{15}=\frac{1\cdot15}{11\cdot15}+\frac{1\cdot11}{15\cdot11}=\frac{15}{165}+\frac{11}{165}=\frac{15+11}{165}=\frac{26}{165} < \frac{1}{2}\\\\\frac{1}{11}+\frac{1}{15}\approx0$

The rectangle shown has a perimeter of 156 cm and the given area. Its length is 6 more than five times its width.

Stells [14]

P=156 cm
l=6+5w
P=2(l+w)
156=2(6+5w+w)
156=2(6+6w)
156=12+12w
12+12w=156
12w=156-12
12w=144
w=12cm

l=6+5•12
l=6+60
l=66cm
