Question

10. The sides of a rectangle are 80 cm
and 60 cm. What is the length of the
diagonal?​

Answer 1

Step-by-step explanation:

length of diagonal, d

length of rectangle l, breadth of rectangle b

d²=l²+b²

= 80²+60²

= 6400+3600

= 10000

d = 100

Answer 2

$\huge{ \pink{\underbrace{ \mathbb{Answer}}}}$

$\bold{Length=80cm}$

$\bold{Breadth=60cm}$

$\bold{d = \sqrt{ {w}^{2} + {l}^{2} } }$

$\bold{ = \sqrt{ {60}^{2} + {80}^{2} } }$

$\bold{ = \sqrt{3600 + 6400} }$

$\bold{ = \sqrt{10000} }$

$\bold{ = 100}$

$\bold{ \therefore \: diagonal \: is \: 100cm.}$
