Question

The perimeter of a triangle is 88 centimeters. If two sides are equally long and the third side is 10 centimeters longer than the​ others, find the lengths of the three sides. The length of each of the two equally long sides is ____(centimeters,square centimeters) and the length of the longer side is ____ (square centimeters,centimeters).

Answer 1

P=2x +2y

2x=2y-p

As given that 2x=2(10)+88

x=108/2

x=54cm

Answer 2

The length of each of the two equally long sides is 26 cm

The length of the longer side is 36 cm

Explanation:

Let the length of each of the two equal sides be represented by x

The other side = 10 + x

Perimeter of triangle (P) = sum of all sides of the triangle

88 = x + x + 10 + x

88 = 3x + 10

3x = 88 - 10

3x = 78

x = 78/3 = 26

Length of each of the two equally long sides (x) = 26 cm

Length of the longer side = 10 + x = 10 + 26 = 36 cm
