• Use Heron's formula

• Heron's formula = √s(s-a)(s-b)(s-c), where s is semiperimeter

• semiperimeter = a+b+c/2 , a,b,c are sides

Required area , A = Area of outer traiangle - Area of inner triangle

• A = √132(132-22)(132-122)(132-120) - √36(36-22)(36-24)(36-26)

• A = √132(110)(10)(12) - √36(14)(12)(10)

• A = √1742400 - √60480

• A = 1320 - 245.9268183830

• A = 1074.073181616 square centimetre
