Question

Someone help pleaseee

Answer 1

see explanation

Explanation:

The area (A) of a rectangle is calculated as

A = length × breadth

= (2 +
`√(2)` )(4-2
`√(2)` ) ← expand using FOIL

= 8 - 4
`√(2)` + 4
`√(2)` - 4 ← collect like terms

= 4 units²

--------------------------------------------------------

The opposite sides of a rectangle are congruent , so

perimeter = 2(4 - 2
`√(2)`) + 2(2 +
`√(2)` ) ← distribute parenthesis

= 8 - 4
`√(2)` + 4 + 2
`√(2)` ← collect like terms

= 12 - 2
`√(2)` units
