Question

the breadth of a rectangle is half the length.the length of the rectangle is 15 cm .find its perimeter​

Answer 1

Answer:

45 cm

Step-by-step explanation:

perimeter of rectangle is 2(l+b)

2(l+b) = 2 ( 15+7.5 )

= 2 ( 22.5 )

=45 cm

Answer 2

length =15cm

breadth =15/2cm

p=2(l+b)

p=2(15+15/2)

p=2×45/2

so perimeter =45cm
