Question

Length of the rectangle 15cm and breadth 8cm fins the diagonal of the rectangle​

Answer 1

Answer:

Length=15cmand breadth=8cm

Lenght of diagonal= \sqrt{l^2+b^2

therfore= \sqrt{ 15^2+8^2

= \sqrt{289=17

Therfore length of the diagonal =17

Answer 2

Step-by-step explanation:

1. LET RECTANGLE BE ABCD
2. WE CHOOSE THE RIGHT TRIANGLE WITH DIAGONAL BD

LET RECTANGLE BE ABCD

WE CHOOSE THE RIGHT TRIANGLE WITH DIAGONAL BD

LENGHT IS 15 CM AND BREADTH IS 8CM THAT IS BC=15CM & DC=8CM

4.IN RT TRIANGLE BDC BD²=BC²+DC²=15²+8²=225+64=289

5.THEREFORE BD=ROOT OF 289=17

LENGTH OF DIAGONAL IS 17 cm
