Question

In an isosceles triangle, the difference between one of the equal sides and the unequal side (longest of the three) is 3/10 of the sum of the equal sides. If the perimeter of the triangle is 90 cm, then find the length of unequal side in centimetres.​

Answer 1

Answer:

Let the equal side of the triangle be x cm <br> Given perimeter of the triangle = 90 cm, then the unequal side

Let the equal side of the triangle be x cm <br> Given perimeter of the triangle = 90 cm, then the unequal side. <br> Given that

Let the equal side of the triangle be x cm <br> Given perimeter of the triangle = 90 cm, then the unequal side. <br> Given that<br>

Let the equal side of the triangle be x cm <br> Given perimeter of the triangle = 90 cm, then the unequal side. <br> Given that<br><br>

Let the equal side of the triangle be x cm <br> Given perimeter of the triangle = 90 cm, then the unequal side. <br> Given that<br><br><br>

Let the equal side of the triangle be x cm <br> Given perimeter of the triangle = 90 cm, then the unequal side. <br> Given that<br><br><br><br>

Let the equal side of the triangle be x cm <br> Given perimeter of the triangle = 90 cm, then the unequal side. <br> Given that<br><br><br><br><br>

Let the equal side of the triangle be x cm <br> Given perimeter of the triangle = 90 cm, then the unequal side. <br> Given that<br><br><br><br><br>Length of the unequal side

Let the equal side of the triangle be x cm <br> Given perimeter of the triangle = 90 cm, then the unequal side. <br> Given that<br><br><br><br><br>Length of the unequal side<br> Hence, the correct option is (a)
