Question

can anyone answer this question??☺☺​

Answer 1

Answer:

As, width = 8

Diagonal = 17

So by applying Pythagoras theorem.

Length² + width² = diagonal ²

Lenght = 15

So,

perimeter = 2(L + B)

= 2(23) = 46cm

Answer 2

Answer:

Given that

Width=8cm and diagonal=17cm

using by Pythagoras theorem we get

sq. of diagonal= sq. of (width + Hight )

= sq of 17 = Sq of (8+h)

= 289 = 64+ h

=) 289-64=sq of h

i.e h=√225

= 15cm

P = 2 (l+b)

2 (15+8 )

2*23=46cm.
