Question

The perimeter of a triangle is 510 cm square and its sides are in the ratio 14 : 12 : 25. What is the measure of greatest side.
• 170cm
• 120 cm
• 250 cm
• 270 cm​

${\huge{\underline{\small{\mathbb{\pink{Lets \ take 1:2:3 \ as \ 1x}}}}}}$${\huge{\underline{\small{\mathbb{\pink{2x \ and \ 3x}}}}}}$

So,

Perimeter of a triangle = Sum of all its sides

100 cm = 1x + 2x + 3x

100 cm = 6x

100/6 = x

16.66 = x

1 x = 1*16.66 = 16.66

2 x= 2*16.66 = 33.32

3 x= 3*16.66 = 49.98

Now we should find the area of th

e area of the triangle through “Heron’s formula”

a =16.66

b = 33.32

c = 49.98

s = a + b + c/2 = 16.66 + 33.32 + 49.98/2 = 99.96/2 = 49.98

s-a = 49.98 - 16.66 = 33.32

s-b = 49.98 - 33.32 = 16.66

s-c = 49.98 - 49.98 = 0

Area of triangle = √16.66 * 49.98 * 33.32 * 0

Area of triangle = 0

${\huge{\underline{\small{\mathbb{\pink{Hence, \ the \ Area \ of \ triangle \ =0}}}}}}$
