Question

The perimeter of rectangle is 20 cm and length is 5 cm Find the area and Diagonal of Rectangle​

Answer 1

Answer:

first we have to find breadth so area of perimeter=2×(l+b)

so 20=2×(5+b)

20=10+2b

20-10=2b

10=2b

b=5cm

then we have to apply pythagoras theorm so it is h^2=p^2+b^2

h^2=25+25

h^2=50

h=

$\sqrt{50}$

h=7.3cm

this is diagonal

area =l×b

=5×5

=25cm^2

Answer 2

b= 5 cm

and

Diagonal is 25 cm ^ 2 , please brainlist plz. i very need
