Question

if the area of an isosceles triangle is 120 CM square and the length of each of its equal side is 17 cm find its base​

Answer 1

Step-by-step explanation:

Area of triangle with three given sides can only be find through the heron's formulae

area of triangle=√s(s-a)(s-b)(s-c)

let , a=17cm

b=17cm

&c= ?

s=a+b+c/2

s=

Answer 2

Its base is 14.12 cm.

Step-by-step explanation:

Since we have given that

Area of isosceles triangle = 120 sq. cm

Length of equal side = 17 cm

We need to find its base.

$Area=\dfrac{1}{2}\times b\times h\\\\120=\dfrac{1}{2}\times b\times 17\\\\\dfrac{240}{17}=base\\\\14.12=base$

Hence, its base is 14.12 cm.
