Question

if the perimeter of rectangle is 30 cm and length is 9 cm then what is the breadth​

Answer 1

Answer:

Let breadth be = x

Length = 9cm

Perimeter = 30m

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

30=2(9+x)

30= 18+2x

=30-18=2 x

=12÷2=x

x=6

$\rightarrow$so,breadth=x=6cm

Answer 2

Step-by-step explanation:

Breadth is 6 cm and and the length is 9cm
