Question

the base of an isosceles triangle is 48 cm and one of its equal side is 30 cm find the area of the triangle​

Answer 1

Answer:

formula is:-

area of isosceles triangle=1/2×b×h

=1/2×48×30

=24×30

=720

so now we know that,

the area of of the triangle is 720

Answer 2

Answer:288√3 cm²

Step-by-step explanation:

Using Heron's Formula,

A= √s(s-a)(s-b)(s-c).

[S is semiperimeter]

=√54*8*24*24

=√2*3*3*3*2*2*2*2*3*2*2*2*3*2*2

=2*2*2*2*2*3*3*√3

=32*9√3

=288√3 cm²
