Question

What is the area of the figure?

Answer 1

Check the picture below.

`\bf \textit{area of a triangle}\\\\ A=\cfrac{1}{2}bh\qquad \qquad A=\cfrac{1}{2}(12√(2))(12√(2))\implies A=6√(2)\cdot 12√(2) \\\\\\ A=6\cdot 12√(2)\cdot √(2)\implies \implies A=72(√(2))^2\implies A=72\cdot 2\implies A=144`
