Step-by-step explanation:

46 cm is the perimeter

Answer 2

Answer:

perimeter = 46 cm

Step-by-step explanation:

$length^{2} + breadth^{2} = diagonal^{2}$

$15^{2} + breadth^{2} = 17^{2}$

breadth = 8 cm

Method 1 to find perimeter

perimeter = sum of length of all 4 sides = 15 + 8 + 15 + 8 = 46cm

Method 2 to find perimeter

perimeter = 2 (Length + Breadth) = 2(15+8) = 46 cm
