Question

A triangular sign in a store has a perimeter of 5.5'. To of the sides of the triangle are the same length while a 3rd Side is 1' longer than those sites. Find out lengths of the sides of the sign

Answer 1

So the perimeter is equal to the sum of all the sides.

Let's call X the length of side one and side 2, and side 3 is equal to x+1.

So,

P= S1+ S2 +S3

5.5 = X + X+ (X+1)

5.5 = 3x+1

4.5 = 3x

1.5 = x

So, the sides' lengths are 1.5, 1.5, and 2.5
