Question

a daigonal of rectangle is 17 cm and the length of its one side is 15 cm.what is the perimeter of the rectangle​

Answer 1

Answer:

breadth = 8 cm

Step-by-step explanation:

$diagonal^{2} = length^{2} + breadth^{2}$ (right angle triangle)

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

$breadth^{2} = 17^{2} - 15^{2} \\breadth^{2} = 289 - 225$

breadth = 8 cm

Answer 2

Answer:

Diagnol of rectangle = 17 cm

One side = 15 cm

Second side = 15 × x

P = 2( l+w)

d= l² + w²

P = 2l + 2 root d² - l²

= 2.15 + 2 root 17²- 15²

= 46 cm
