Question

by using heron's formula find the area of triangle of side 30;9; 30cm​

Answer 1

Answer:

Step by step explaination

s=1/2 * (30+30+9)

s= 1/2 × 69

s = 34.5

(s-a) = 34.5 - 30 = 4.5

(s-b) = 34.5 - 30 = 4.5

(s-c) = 34.5 -9 = 25.5

Area of triangle = √s× (s-a) (s-b) (s-c)

= √34.5× 4.5× 4.5×25.5

= 133.47 cm^2
