Question

length and breadth of a rectangular field are in the ratio 5:4 if width of the field is 36m what is its length?

Answer 1

Given:

We have ratio of length and breadth of rectangular field is 5:4. And width is 36m.

To Find:

We need to find the length of field?

Step-by-step explanation:

• Since, we have ratio of length and breadth of rectangle is 5:4

• Let the lenght of rectangle be 5x and breadth of rectangle be 4x

• Now we have given that breadth of rectangle is 36m

• Thus we can write it as

                        $4x=36\\x=9$

• Hence we can find the length of rectangle is 5x=5$\times$9=45

• Thus we can find the perimeter of rectangle by the formula

               Perimeter=2(l+b)=2(36+45)=145m

Hence, perimeter is 145m and length of rectangle is 45m.
