Question

The sides of a triangle are in the ratio of 25:14:12 and its perimeter is 510 m. The greatest side of the triangle is

Answer 1

Answer:

250 m.

Step-by-step explanation:

Let the sides be 25x , 14x, 12x.

The perimeter is 510 m.

25x+ 14x+ 12x = 510

51x=510

x=10

Largest side:- 25x= 25×10=250 m

Answer 2

Answer:

Let the sides to be 25x, 14x and 12x.

Perimeter = Sum of three sides

510m = 25x + 14x + 12x

510m. = 51x

510m / 51 = x

.

. . x = 510/ 51 = 10

Sides = 25x = 25× 10 = 250m

14x = 14 × 10 = 140 m

12 x = 12 × 10 = 120 m

The greatest side of the triangle is 250 m.
