Question

4) Find the diagonal of a rectangle whose length is 35cm and breadth is 12cm .​

Answer 1

Answer:

37

Step-by-step explanation:

Diagonal of a rectangle =

$\sqrt{ {l}^{2} + {b}^{2} }$

So , Diagonal =

$\sqrt{ {35}^{2} + {12}^{2} }$

= square root of 1369 = 37

Answer 2

Step-by-step explanation:

suppose, ABCD is a rectangle.

l=35cm

b=12cm

let,

In triangle ABC,

(AB)^2 + (AD)^2 = (BD)^2

(12)^2 + (35)^2. = (BD)^2

144 + 1225. = (BD)^2

1369. = (BD)^2

Taking squareroot

37. = BD

BD = 37cm

Therefore, diagonal of rectangle is 37 cm
