Question

If the perimeter of an isosceles triangle is 11 cm and its base is 5 cm,then find the area of the triangle. ​

Answer 1

7½ cm

Step-by-step explanation:

If the base is 5cm than we have a side is 3cm

So the base is 5cm and sides are 3 cm and 3 cm

Then the area would be ½ × base× height

= ½ x 5 x 3 = 7½ cm
