Question

What is the area? Please explain steps so I can attempt to understand

Answer 1

Answer:

$12 \sqrt{2}$

Step-by-step explanation:

you can use hypotenuse formula

45-45-90 isosceles right triangle

so, 45= x

x² + x² = 24²

2x² = 24²

x²= 24.12

x= $\sqrt{288} = 12 \sqrt{2}$

or :

you can use this rule: if you see a 45 45 90 isosceles right triagngle (you can look picture) 45=a cm and 90 = $a\sqrt{2}$

cm

so ;

$a \sqrt{2} = 24$

a= $12 \sqrt{2}$

hope this helps ^-^
