Question

an isosceles triangle has perimeter 50 cm and each of the equal side is 17 cm find the area of the triangle​

Answer 1

Answer:

60 cm ²

Step-by-step explanation:

perimeter = 50 cm

3rd side = 50-17×2 = 16

triplate ( 8 ,15, 17)

area = ½× base×height

= ½×8×15= 4× 15 = 60 cm² ans.

Answer 2

Step-by-step explanation:

let the sides of the triangle be a,a,b

and a=17 and 2a+b=50

b=16

by herons formula the area =√(s)(s-a)(s-a)(s-b)

s=(2a+b)/2 = 25

area=√25*8*8*9

area=5*8*3=120cm²
