Question

if each side of a triangle
halved then its perimeter will be decreased by (a) 100% (6) 50% Length of perpendicular drawn on smallest side of a scalene triangle is (c) 25% (d) no I want complete by step by step ​

Answer 1

Answer

Decreased By 50%

Example:-

Triangle Of:

A = 2cm

B = 9cm

C = 3cm

Formula => P = A + B + C

P = (A + B + C) × 50/100

P = (2 + 9 + 3) × 1/2 ------> { 100/2 = 50, Hence 1/2}

P = ( 11 + 3 ) × 1/2

P = 14 × 1/2

P = 14/2

P = 7cm
