Answer 2

Answer:

area of. a right angle triangle is

1/2×base×height

therefore 1/2×15×height=60

15×height=60×2

15×height=120

height=120/15

height=8

therefore

now using Pythagoras property

a²+b²=c²

8²+15²=c²

64+225=c²

289=c²

√289=c

17cm=c

therefore hypotenuse is equal to 17

height is equal to 8

base is equal to 15

now perimeter=sum of all sides

=17+15+8

=40cm
