Question

The perimeter of a triangular field is 300cm and its sides are in the ratio 5: 12:13. Find the area of the triangular field?

Answer 1

Answer:

3000cm^2

Step-by-step explanation:

Sides -

a = 5x

b = 12x

c = 13x

Perimeter = Sum of all sides

=> 5x + 12x + 13x = 300

=> 30x = 300

=> X = 300/30

X = 10

Sides -

a = 5 × 10 = 50cm

b = 12 × 10 = 120cm

c = 13 × 10 = 130cm

Area of triangle

Area √s (s-a) (s- b) (8-0) , (s = a+b+c/2)

50 +130 +130/2

= 150 cm

Area = √150 (150-50) (150-120) (150-130)

=√150 (100) (30) (20)

=3 X5 X 2 X 5 X 2×2 X5 X5 X 2 X3 X5 X

=3 x 5X5 X5x2x2x2

=3000 cm²
