Question

find the length of the diagonal of a rectangle whose sides are 9cm 40 cm also find the perimeter of the rectangle
with full solutions​

Answer 1

we know that the perimeter of the rectangle is 2(l+b)=2(40+9)=98cm

Answer 2

Step-by-step explanation:

Diagonal of rectangle =

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

$= \sqrt{ {40}^{2} + {9}^{2} }$

$= \sqrt{1681} = 41$

So, the diagonal is 41 cm.

Perimeter of rectangle = 2(l+b)

=2(40+9)

[2×49 = 98 cm
