Question

I need this answered, please and thanks

Answer 1

P =
`(28√(2) )/(2)` units

A = 24.5
`unit^(2)`

Explanation:

Length of one side

sin
`45^(o)` =
`(x)/(7)`

7sin
`45^(o)`= x

7(
`(√(2) )/(2)`)= x

`(7√(2) )/(2)` = x

Perimeter = 4(
`(7√(2) )/(2)`) =
`(28√(2) )/(2)`

Area = (
`(7√(2) )/(2)`)(
`(7√(2) )/(2)`) =
`(98)/(4)` =24.5
