Question

find the area of a triangle two sides of which are 60cm and 100 cm and the perimeter is 300cm

Answer 1

Answer:

1/2×b×h

=1/2×100×60

=200×60

12000

Answer 2

Step-by-step explanation:

let the other side be x

then,

60+100+x=300

x=140cm

so perimeter of triangle

=300÷2

150cm

area of triangle=√150(150-60)(150-100)(150-140)

=√150×90×50×10

=1500√3
