Question

Find the perimeter of rectangle.If area of rectangle is 100cm² and length is 50cm.​

Answer 1

Area of rectangle given - 100 cm^2

area = Length × breadth .

100cm^2 =50cm × breadth

so breadth = 100/50

= 2cm

Now we can find the perimeter of rectangle

perimeter = 2(L+B )

= 2(50cm+2cm)

=2×52

= 54 cm
