Question

The side of a triangle are in the ratio of 25 : 14 : 12 and its perimeter is 510m. The greatest side of the triangle is (a) 120 m (b) 170 m (c) 250 m (d) 270 m​

Answer 1

Answer:

Step-by-step explanation:

The lengths are 250 m, 140 m and 120 m. Therefore, the greatest side of a triangle is 250 m

Answer 2

AnSwer -:



The option “C” is correct _______________________________
Explanation-:

Perimeter of triangle-:

“P= a + b + c”

P = perimeter

A = Length of first side

B = length of second side

C = length of third side

Now ,

Given,

The length three sides of triangle are in

ratio-:25 : 14 :12

The perimeter of triangle is 510 m

To find ,

The greater side of triangle

_______________________________

Let the length of three sides of triangle

be 25x , 14x and 12 x

Now ,

Perimeter of triangle-:

“P= a + b + c”

P = perimeter = 510 m

A = Length of first side= 25 x

B = length of second side= 14 x

C = length of third side= 12 x

Now ,

25x + 14x + 12x = 510 m

39x + 12x = 510 m

51 x = 510 m

X = 510/51

X = 10

Now ,

Length of first side of the triangle-: 25x

25 x 10 = 250 m

Length of second side of triangle-: 14x

14 x 10 = 140 m

Length of third side of triangle-: 12 x

12 x 10 = 120 m

Therefore,

The greater side of triangle is 250 m

Hence ,

The option “C” is correct
