its perimetre​

Answer 1

Answer:

727 is the perimeter of triangle

Answer 2

Answer:

7(2+2)

Step-by-step explanation:

Given the congruent side = 7 cm or Perpendicular (P) = Base (B) = 7 cm

Since, the triangle is a right angled isosceles triangle,

H2=B2+P2

H2=72+72

H=72 cm

Perimeter = P + B + H

= 7+7+72

= 14+72

= 7(2+2)
