Question

10. The adjacent sides of a rectangular field are
8 m and 6 m, then its diagonal is
(a) 9 m (b) 11 m (c) 12 m (d) 10 m​

Answer 1

Step-by-step explanation:

through Pythagoras theorem

64+ 36 = 100

10^2 = 100

answer = 10....!!!!

option D

hope it helps you.....☺☺

Answer 2

$\underline{\orange{\bf Given :-}}$

• Length of rectangle = 8 m
• Breadth of rectangle = 6 m

$\underline{\orange{\bf To \: Find :-}}$

• Length of diagonal

$\underline{\orange{\bf Solution :-}}$

We have,

• Length of rectangle = 8 m
• Breadth of rectangle = 6 m

We know that,

$\boxed{\sf Hypotenuse^{2} = Perpendicular^{2} + Base^{2}} \: \: \: [\bf Pythagoras \: theorem ]$

Substituting the values of perpendicular and base we get,

$\implies$Hypotenuse^2 = 6^2 + 8^2

$\implies$Hypotenuse^2 = 36 + 64

$\implies$Hypotenuse^2 = 100

$\implies$Hypotenuse = $\bf\sqrt{100}$

$\implies$Hypotenuse = 10 m

Hence, Option d is correct.
