Question

if a rectangular field measures 8 cm by 20 m then the ratio of length to its perimeter is?​

Answer 1

GIVEN:

Length of rectangular field=8 m

Breadth of rectangular field =20 m

To Find:

Perimeter of rectangular field=?

Ratio of length and perimeter=?

Solution:

$\bf Perimeter \: of \: RECTANGULAR \: field=2(l+b)$

$\\ \tt: \implies =2(8+20)$

$= 16 + 40 \\ \\ = 56m$

$\bf Ratio \: of \: length\:and\:rectangular \:field=\frac{l}{p}$

$\\ \tt: \implies =\frac{8}{56}$

$\\ \tt: \implies =\frac{1}{7}$
