Question :- The sides of a triangle are 7/12cm 11/4m and 16/5cm. Find its perimeter.
Given :- The sides of a triangle are 7/12cm 11/4m and 16/5cm.
To find :- perimeter of the triangle.
Solution :- perimeter of the triangle = 1st side + 2nd side +3rd side
= 7/12 + 11/4 + 16/5 { taking LCM of 12, 4 & 5 }
= 35/60 + 165/60 + 192/60
= { 35 + 165 + 192 }/60
= 392/60
= 98/15
==> the perimeter of the triangle = 98/15
