Answer 1

Question;


The base of an isosceles triangle is 24cm and it's area is 60cm^2. find it's perimeter

Method of Solution:

Given:

Base of Isosceles Triangle = 24 cm

Area of Isosceles Triangle = 60 cm²

We know that Formula of Isosceles Triangle = b/4×√4a²-b² = 60

24/4×√4a² -(24)² = 60

6×√4a²- 576 = 60

6×2a-24 = 60

12a = 60+24

12a = 84

•°• a = 7

Therefore, Side of Isosceles Triangle is 7


Now, According to the Question statement!


We know that Formula of Isosceles Triangle = 2a+b

2(7) + 24

14 + 24

=> 38

Hence, Perimeter of Isosceles Triangle is 38 cm
