Question

what is the answer for this one ​

Answer 1

Answer:

0 cm²

Step-by-step explanation:

Perimeter of Triangle = 150 cm

Ratio = 5:2:3

= 5x + 2x + 3x = 150 cm

10x = 150

x = 15

First side = 5 × 15 = 75 cm

Second side = 2 × 15 = 30 cm

Third side = 3 × 15 = 45 cm

Area of triangle = Heron's Formula

Heron's Formula = √s (s - a) (s - b) (s - c)

Where s is semi perimeter.

= 150/2

= 75 cm

= √75 (75 - 75) (75 - 30) (75 - 45)

= √75 × 0 × 45 × 30

= √0 = 0 cm²
