Answer 1

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

$\bf \small \:perimeter = 2(l + b)$

$\bf \small \:48 = 2(4x + x)$

$\bf \small \:48 = 2(5x)$

$\bf \small \:48 = 10x$

$\bf \small \:x = \frac{48}{10}$

$\bf \small \:x = 4.8$

$\bf \small \:\therefore \: breadth \: is \: 4.8m$

Finding length

$\bf \small \:length = 4x$

$\bf \small \: = 4 \times 4.8$

$\bf \small \: = 19.2$

$\bf \small \: \therefore \: length \: is \: 19.2m$

Answer 2

Answer:

length = 19.2 m

breadth = 4.8 m
