Question

What will be the perimeter of an isosceles A ABC with two of its sides measuring 30 cm and 65 cm?​

Answer 1

125cm

Explanation:

$perimeter \: of \: Isosceles \: triangle = 2a + b$

$perimeter = 2(30)cm + 65cm$

$perimeter = 2 \times 30cm + 65cm$

$perimeter = 60cm + 65cm$

$perimeter = 125cm$

Therefore, the perimeter is 125cm

Answer 2

Answer:

125 cm

Step-by-step explanation:

Perimeter of an isosceles triangle = (2a + b)

= 2 × length of one of the equal sides + third side

= 2(30) + 65

= 60 + 65

= 125 cm
