Answer: 4x + x = 35 or 5x = 35
Step-by-step explanation:
Let the short side of triangle is x unit,
Thus, According to the question,
The other longer sides are 2x and 2x,
Thus, the perimeter of the isosceles triangle = 2(2x) + x = 4x + x
But, the perimeter of the triangle = 35 inches,
⇒ 4x + x = 35
⇒ 5x = 35
⇒ x = 7
Therefore, the measurement longer sides of the triangle = 2x = 2×7 = 14 inches
And the measurement of the shorter side = x = 7 inches
