Question

find the area of an isosceles triangle measures 80 cm and its area is 360 cm square. find the perimeter of the triangle

Answer 1

Answer:

perimeter=162cm

Step-by-step explanation:

area of triangle=1/2 base*height

360=1/2*80*h

h=360/40

h=9cm

by pythagoras theorem

(ab)²=ad²+bd²

(ab)²=81+1600

(ab)²=1681

(ab)=√1681

(ab)=41

perimeter=41+41+80

perimeter=162cm
