48 cm 73 cm 55 cm​

Answer 1

Answer:

area of triangle for scalene triangle is using herons formula

Answer 2

Answer:

Let

a = 48 cm

b = 73 cm

c = 55 cm

Heron's formula = a + b + c / 2

===> 48 + 73 + 55 / 2

===> 176 / 2

===> 88

We know that

√ s ( s - a ) ( s - b ) ( s - c )

√ 88 ( 88 - 48 ) ( 88 - 73 ) ( 88 - 55 )

√ 88 ( 40 ) ( 15 ) ( 33 )

√ 11 × 8 × 8 × 5 × 3 × 5 × 3 × 11

11 × 8 × 5 × 3

1320 cm² .
