Answer 1

Step-by-step explanation:

P = 12x + 17x + 25x

540 = 54x

x = 10

12x = 120

17x = 170

25x = 250

Answer 2

Answer:

As we know that the perimeter of triangle = Sum of all three sides of Triangle....

Therefore LET side be 12x , 17x , 25x

By adding .....

54x = 540

x = 540/54

x = 10cm

NOW Longest side here is Hypotenuse......25x = 250 cm

THEREFORE base and height are 170 cm and 120 cm

now area of Triangle is EQUAL TO 1/2 * B * H

= 1/2 * 170* 250

21,250 cm² = 2.125 m²
