Question

the length of a rectangular field is three times its breadth.if the breadth of the field is 8 cm, find the perimeter of the field.

Answer 1

Given

Breadth =8cm

And length is 3 times of Breadth

Then Length =3x8=24cm

Perimeter of rectangle =2(l+b)

=2(8+24)

=2x32=64cm

This is ur ans hope it will help you

Answer 2

Answer:

⇒ Perimeter = 64 cm

Step-by-step explanation:

The breadth of the rectangle is given to be 8 cm

Given that the length of the rectangle is 3 times the breadth

So, Length of the rectangle = 3 × breadth of rectangle

⇒ Length of rectangle = 3 × 8 = 24 cm

So, Perimeter = 2( Length + breadth)

⇒ Perimeter = 2(24 + 8)

⇒ Perimeter = 2 × 32

⇒ Perimeter = 64 cm
