Question

the length and breadth of a rectangular field are in the ratio 5:3 if its perimeter is 128 M find the dimensions of the field​

Answer 1

Let the Length and breadth be 5X and 3X

Perimeter of the field = 128

2(L+B) = 128

2(5X+3X) = 128

2 × 8X = 128

8X = 128/2

8X = 64

X = 64/8

X = 8.

Therefore,

Length of the field = 5X = 5 × 8 = 40 CM

Breadth of the field = 3X = 3 × 8 = 24 CM.

Answer 2

Let. l:b=5:3
5x&3x
perimeter of rectangle=2(l+b)
128=2(5x+3x)
128=2(8x)
128/2=8x
64=8x
64/8=x
8=xor
x=8
5x=5×8=40,
3x=3×8=24,

so,the dimension of 24&40
