Question

how to find the breadth of a rectangle, if diagonal = 17cm and length = 15cm.
use pythagoras theorem

Answer 1

Answer:

breadth = 8 cm

Step-by-step explanation:

by Pythagoras theorem :

17^2 = 15^2 + breadth^2

289-255 = breadth^2

√64 = breadth

breadth = 8 cm

Answer 2

Answer:

8 cm

Step-by-step explanation:

Using pythagoras theorem,

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

• $breadth = \sqrt{ {diagnal}^{2} - {length}^{2} }$
• $breadth \: = \sqrt{ {17}^{2} - {15}^{2} }$
• $breadth = \sqrt{289 - 225}$
• $then.breadth = \sqrt{64}$
• Hence the required breadth = 8 cm
