Question

Find the approximate length of the diagonal of rectangular piece of land whose sides are 8 m and 5 m
​

Answer 1

Answer:

diagonal =√l^2+b^2

=√8^2+5^2 m

=√64+25 m

= √89 m

= 9.33 m

Answer 2

Answer:

Answer:

Diagonal of the rectangle (d)=17cm

Explanation:

Given Dimensions of a rectangle:

Length (l) = 15 cm

Breadth (b) = 8 cm

Let diagonal = d

_______________________

We know that,

\boxed {Diagonal (d)=\sqrt{l^{2}+b^{2}}}Diagonal(d)=l2+b2

________________________

\implies d = \sqrt{(15)^{2}+8^{2}}⟹d=(15)2+82

\implies d = \sqrt{225+64}⟹d=225+64

\implies d = \sqrt{289}⟹d=289

\implies d = \sqrt{17^{2}}⟹d=172

\implies d = 17\: cm⟹d=17cm

Therefore,

Diagonal of the rectangle (d)=17cm
