= √289 - √64
= √225
= 15 cm
2.) Sisi segitiga siku siku
= √11² + √60²
= √121 + √3600
= √3721
= 61 cm
3.) Diagonal = √12² + √5²
= √144 + √25
= √169
= 13 cm
=√17² - √8²
=√289-√64
=√225 = 15 cm (a)
2. c = √a²+√b²
= √60²+√11²
= √3600+√121
= √3721 = 61 cm (c)
3. diagonal = √p²+√l²
= √12²+√5²
= √144+√25
= √169 = 13 cm (b)
