Question

the length and breadth of a rectangular Park are in the ratio 7:4 and its area is 17500 square meters find the perimeter of the field.​

Answer 1

Answer:

perimeter = 960

Step-by-step explanation:

Perimeter of rectangle = 2(l+b)

given length and breadth in ration 5:3

therefore l = 5x and b=3x.

2(5x+3x)=128

= 2(8x) = 128 =

16x = 128 = x= 8.

l = 5*8 = 40

and b= 3*8 = 24.

Area of rectangle = l*b = 40*24 = 960.

The Answer is 960

Answer 2

Answer:

Let the length of the rectangular park be 7x and breadth of the rectangular park be 4x

Step-by-step explanation:

Area of rectangle=l×b

17500=7x×4x

28x²=17500

x²=17500/28

x=√625

x=25

7x=7×25=175

4x=4×25=100

Perimeter of rectangle=2{l+b}

=2(175+100)

=2(275)

=550

Perimeter of rectangular park is 550 m
