Question

the perimeter of a triangle field is 144 m and the ratio of sides is 3:4:5.

Answer 1

The perimeter of triangle = 144 m
Ratio of their sides = 3 : 4 : 5
Sum = 3 + 4 + 5 = 12
THEREFORE, first side = (3 x 144) / 12
= 3 x 12 = 36 m
Second side = (4 x 144) / 12
= 4 x 12 = 48 m
Third side = (5 x 144) / 12
= 5 x 12 = 60 m

Answer 2

Perimeter of the triangle means s+s+s
so let the side be x.
then the equation must be 3x+4x+5x=144m
= 12x =144m
= x =144/12= 12
so x is equal to 12.
thus, 3x = 3×12 =36
4x= 4×12 =48
5x= 5×12 =60.
so all three sides r 36, 48 and 60.
