Question

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

Answer 1

`12 √(2)`

Explanation:

you can use hypotenuse formula

45-45-90 isosceles right triangle

so, 45= x

x² + x² = 24²

2x² = 24²

x²= 24.12

x=
`√(288) = 12 √(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√(2)`

cm

so ;

`a √(2) = 24`

a=
`12 √(2)`

hope this helps ^-^
