Question

the base of an isosceles triangle is 30cm
and area is 120 cm2 find the perimeter of
the
a triangle ​

Answer 1

Answer:

Step-by-step explanation:

Perimeter of an isosceles triangle is b+√b^2+16(a/b)^2,

Where b is base and a is area,

Substitute the values given,

30+√30^2+16(120/30)^2,

30+√30^2+16(4)^2,

30+√30^2+16(16),

30+√30^2+2(2),

30+30+4,

64 cm,

So,64 cm is the perimeter of the isosceles triangle.
