Answer 1

Answer:

56cm

Step-by-step explanation:

find the perimeter of rectangle whose length is 16 cm and diagonal is 20 cm

Answer :-

Perimeter of rectangle = 56

Given :-

length of rectangle ( l ) = 16cm

Diagonal of rectangle ( d )= 20cm

To find :-

Find the perimeter of rectangle = ?

Solution :-

Length = 16cm

==>> 56cm

$\underline\mathfrak\red{let's\:find:-}$

give::--

• length= 16cm
• diagonal=20cm
• perimeter= p

using formula:- .

P= 2(l+b)

D= √b²+l²

solving for perimeter:-

= P = 2l+2 √d²-l²

= P= 2•16 + 2•√20²-16²

= P= 56cm

hence perimeter is 56cm.
