11.

the breadth of a rectangle Garden is 2 by 3 of its length if its perimeter is 40 metre find its length and breadth

Answer»

LENGTH of rectangle : 2/ 3×breadth m

Perimeter of rectangle : 40m

Perimeter of rectangle : 2 ( L + B)

40 : 2 ( 2/3B + B)

40 : 4/3B + 2B

40× 3/4 : B + 2B

30 : 3B

30/3 : B

10M : B

Therefore breadth of rectangle is 10 m

Length of rectangle : 2/3 × B

If 231325x is divisible by 9, then find the least value of x.

Answer»

$<klux>GIVEN</klux> \: <klux>NUMBER</klux> \: 231325\pink {x}$

$\underline { \blue { Divisibility \: rule \:of \:9 :}}$

The given number is divisible by 9, only if the sum of the DIGITS is multiple of 9 .

$Here , Sum \:of \:the \:digits \: of \:231325\pink {x} \\= 2+3+1+3+2+5+\pink {x} \\= 16 + x$

$Now, 16 + \pink {x} = 18 \\(Least \:multiple \:of \:9 )$

$\implies \pink {x}= 18 - 16$

$\implies \pink {x} = 2$

Therefore.,

$\red { Least \: value \: \pink {x} } \green { = 2 }$

17.

Diagonal of a rectangle is 25 cm and length is 20 cm find the area of rectangle

Answer»

$\huge\mathbb{\underline{SOLUTION:-}}$

$\sf\underline{\purple{\:\:\:\:Given\:\:\:\:}}$

$\sf\bullet diagonal \:of\: Rectangle=25cm\\ \\ \sf\bullet <klux>LENGTH</klux>\:of\: Rectangle=20cm$

Now by Pythagoras

$\boxed{\sf{Hypotenuse {}^{2}=base{}^{2}+perpendicular {}^{2}}}$

$\sf\implies (25){}^{2}=(20){}^{2}+b{}^{2}\\ \\ \sf\implies 625=400+b{}^{2}\\ \\ \sf\implies 625-400=b{}^{2}\\ \\ \sf\implies 225=b{}^{2}\\ \\ \sf\implies \sqrt{225}=b\\ \\ \sf\implies b=15cm$

Now the AREA of rectangle

whose

Length =20cm
Breadth=15cm

$\boxed{\sf{Area\:of\: rectangle=length\times breadth}}$

$\sf\implies Area\:of\: rectangle=15\times 20\\ \\ \sf\implies Area=300cm{}^{2}$

$\boxed{\sf{\red{Area\:of\: rectangle=300cm{}^{2}}}}$

Answer» Step-by-step explanation: The sum of 5 no. = 2+3+7+8+9 = 29 The average of 4 no. is = 6 (Given) so, Sum of 4 no. = 6×4 = 24 Then, The 5th no be. = ( Sum of 5 no.s - Sum of 4 no.s ) = 29 - 24 = 5 ans. Hope it will help you

50.

Here are 5 numbers- 2 5 7 8 9one of the cards is removed and the mean average of the 4 remaining numbers is 6which card was removed?

Answer»

Step-by-step explanation:

The sum of 5 no. = 2+3+7+8+9

= 29

The average of 4 no. is = 6 (Given)

so, Sum of 4 no. = 6×4

= 24

Then, The 5th no be.

= ( Sum of 5 no.s - Sum of 4 no.s )

= 29 - 24

= 5 ans.

Hope it will help you
