√10 + √2 cm
√10 -√2 cm
Find the perimeter
To find the perimeter, we need to add the lengths of all sides. The given sides are √10 + √2 cm and √10 - √2 cm.
Perimeter = (√10 + √2 cm) + (√10 - √2 cm)
When we combine like terms, √2 and -√2 will cancel each other out, and we are left with:
Perimeter = (√10 + √10) cm
Simplifying further:
Perimeter = 2√10 cm
