Answer 1

Given :

• area of a isosceles triangle with altitude 15cm and one of the equal side 17 cm

To find :

• find the area of a isosceles triangle

Solution :

Area of a isosceles triangle

= a/4 √4b² - a²

= 15/4 √4 × 17² - 15²

= 15/4 √4 × 64

= 15/4 √256

= 15/4 × 16

= 15 × 4

= 60 cm²

∴ Area of a isosceles triangle is 60 cm²
