Question

the length and breadth of field is in the ratio 13 :11 if the length of the field is 3m406cm then find the perimeter of the field​

Answer 1

Hey mate.

Given length=3.406m

=340.6cm

Ratio between Length and breath =13:11

13 : 11=340.6 : x

13x=340.6×11

13x=3746.6

x=3746.6/13

X=288.2cm. (or) 2.882 m

Lastly we shy find perimeter of the given rectangular shape:-

=2(l+b)

=2(3.406+2.882)

=2(6.288)

=12.576

Hope it will help you

Answer 2

Answer:-

Given:-

length = 3.406 m = 340.6 cm

ratio of length and breadth = 13 : 11

To Find:-

Perimeter

Formula to be used:-

Perimeter of rectangular field that is  2 (l + b)

Solution:-

Ratio = Length : Breadth

13 : 11 = 304.6 : x

13 x = 11 × 304.6

x = 11 × 304.6/13

x = 288.2 cm = 288.2/100 = 2.882 m

Perimeter of rectangular field = 2 (l + b)

Putting All values, we get

= 2(3.406 + 2.882)

= 2 × 6.288

= 12.576 m

Hence, Perimeter of rectangular field is 12.576 m .
