Question

find the perimeter of a diagonal 10cm and the length is 8cm.​

Answer 1

Answer:

Let breath be = x

Using Pythgoras Theorem

=Hypotenuse = height+base

$= {10}^{2} = {8}^{2} + {x}^{2} \\ \\ = 100 = 64 + x \\ \\ = 100 - 64 = x \\ \\ = x = 36 \\ \\ = {x}^{2} = {6}^{2} \\ \\ = x = 6cm$

Finding Perimeter -

$\color{black}\boxed{\colorbox{saffron}{Perimeter-2(length+breadth) }}$

= 2(8+6)

= 2(14)

= 28cm
