Question

two sides of a triangle is 22cm and 28cm the perimeter of the triangle is 70cm what is its third side​

Answer 1

Answer:

we know that perimeter be sum of all side

so

we take third side as x

Then..

x+22x+28x=70cm

51x=70cm

x=70/51

so third side be 70/ 51

Answer 2

perimeter of triangle = l+b+h

in this question we have:-

lenght[l] = 22

breadth [b] = 28

height= let take this as X

the perimeter of the triangle in this question is = 70

hence

22+28+X=70

50+X=70

X=70-50

the answer of the question is 20
