( 2 sin 60) (3 cos 60) +3 tan30

Answer»

Answer:

18 + √3

Step-by-step explanation:

( 2 SIN 60) (3 cos 60) +3 tan30

= (2x(√3)/2)(3x(√3)/2) + 3 X (1/√3)

= 2√3 x 3√3 + (√3x√3)/3

= 6 x √3 x √3 + √3

= 6 x 3 + √3

= 18 + √3

The area of a square playground is 296.48 square metres. Find the length of its side correct to three decimal places.

Answer»

$\huge\sf\red{Given\::-}$

$\sf\gray{Area\:of \:square \:playground\: =\: 296.48m^2}$

$\huge\sf\blue{To\:Find\::-}$

$\sf\gray{Length\: of\: its\:side\: correct\: to\: 3\: decimal\: places}$

$\huge\sf\purple{Solution\::-}$

${\boxed{\sf{\orange{Area\: of \:square \:=\: side\:\times\: side}}}}\\$

$\hookrightarrow \sf \green{Side\:\times \:Side \:=\: 296.48}$

$\hookrightarrow \sf\green {Side^2\: = \:296.48}$

$\hookrightarrow \sf\green {Side\: =\: \sqrt{296.48}}$

$\hookrightarrow \sf\green {Side\: = \:17.218m}$
