Answer:

Given :-

perimeter = 48m

length = 4 × breadth

Required Answer :-

length is 19.2 m

breadth is 4.8 m

Solution :-

Let the breadth of a rectangular field be x

let the length of a rectangular field be 4x

[tex]\bf \small \:perimeter = 2(l + b) [/tex]

[tex]\bf \small \:48 = 2(4x + x)[/tex]

[tex]\bf \small \:48 = 2(5x)[/tex]

[tex]\bf \small \:48 = 10x[/tex]

[tex]\bf \small \:x = \frac{48}{10} [/tex]

[tex]\bf \small \:x = 4.8[/tex]

[tex] \bf \small \:\therefore \: breadth \: is \: 4.8m[/tex]

Finding length

[tex]\bf \small \:length = 4x[/tex]

[tex]\bf \small \: = 4 \times 4.8[/tex]

[tex]\bf \small \: = 19.2[/tex]

[tex]\bf \small \: \therefore \: length \: is \: 19.2m[/tex]

Answer:

length = 19.2 m

breadth = 4.8 m

hope it helps you
