Answer» Option b Step-by-step explanation: Given:- In a RHOMBUS, the length of the two diagonals are 3 meters and 4 meters respectively. To find:- Find its Perimeter? Solution:- The LENGTHS of the two diagonals are 3 m and 4 m Consider a ABCD rhombus AC = 3m and BD = 4 m We know that The diagonals bisect to each other at 90° AO = OC AO = AC/2 = 3/2 cm = 1.5 m BO=OD BD = BO/2 = 4/2 = 2 m ∆AOB is a RIGHT ANGLED triangle By PYTHAGORAS theorem: The square of the hypotenuse is equal to the sum of the squares of the other two sides =>AB^2 = AO^2+OB^2 =>AB^2 = (1.5)^2+2^2 =>AB^2 = 2.25 +4 =>AB^2 = 6.25 =>AB=√6.25 =>AB=2.5 m The length of the side=2.5 m We know that All sides are equal in a rhombus =>AB=BC=CD=DA=2.5m Perimeter of a rhombus = Sum of all sides =>Perimeter=4×length of its side =>P=4×2.5m =>P=10 m Answer:- Perimeter of the given rhombus is 10 m Used formulae:- The diagonals bisect to each other at 90° All sides are equal in a rhombus Pythagoras theorem: The square of the hypotenuse is equal to the sum of the squares of the other two sides Perimeter of a rhombus=4×length of its side

5) In a rhombus, the length of the two diagonals are 3 meters and 4 meters respectively.Find its perimeter. a)14 mb)10 mc)5 md)7 m

Answer»

Option b

Step-by-step explanation:

Given:-

In a RHOMBUS, the length of the two diagonals are 3 meters and 4 meters respectively.

To find:-

Find its Perimeter?

Solution:-

The LENGTHS of the two diagonals are 3 m and 4 m

Consider a ABCD rhombus

AC = 3m and BD = 4 m

We know that

The diagonals bisect to each other at 90°

AO = OC

AO = AC/2 = 3/2 cm = 1.5 m

BO=OD

BD = BO/2 = 4/2 = 2 m

∆AOB is a RIGHT ANGLED triangle

By PYTHAGORAS theorem:

The square of the hypotenuse is equal to the sum of the squares of the other two sides

=>AB^2 = AO^2+OB^2

=>AB^2 = (1.5)^2+2^2

=>AB^2 = 2.25 +4

=>AB^2 = 6.25

=>AB=√6.25

=>AB=2.5 m

The length of the side=2.5 m

We know that

All sides are equal in a rhombus

=>AB=BC=CD=DA=2.5m

Perimeter of a rhombus = Sum of all sides

=>Perimeter=4×length of its side

=>P=4×2.5m

=>P=10 m

Answer:-

Perimeter of the given rhombus is 10 m

Used formulae:-

The diagonals bisect to each other at 90°
All sides are equal in a rhombus
Pythagoras theorem:

The square of the hypotenuse is equal to the sum of the squares of the other two sides

Perimeter of a rhombus=4×length of its side

$\tt{\implies Their\: monthly\:_{(income)}=x}$

$\tt{\implies Their\: monthly\:_{(expenditure)}=y}$

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

$\tt{\implies Their\: monthly\:_{(income)}=6:5}$

$\tt{\implies Their\: monthly\:_{(expenditure)}=5:4}$

$\tt{\implies Their\: monthly\:_{(savings\: each)}=2500}$

$\sf\small\underline\purple{To\: Find:}$

$\tt{\implies Their\: monthly\:_{(income)}=?}$

$\sf\small\underline\purple{Solution:}$

To calculate the monthly income of Amit and Atul, as per the question we have to set us equation then SOLVE both equation by solving we get the value of x and y then we can easily calculate their income. In question, given that monthly income of Amit & Atul are in the ratio 6:5 .The ratio of their monthly expenditure is 5:4 . If each of them saves ₹2500 per month .Find their monthly INCOMES:-]

$\sf\small\green{\implies Amit\:_{(Income)}-Amit\:_{(expenditure)}=Amit\:_{(savings)}}$

$\tt{\implies 6x-5y=2500-----(i)}$

$\sf\small\green{\implies Atul\:_{(Income)}-Atul\:_{(expenditure)}=Atul\:_{(savings)}}$

$\tt{\implies 5x-4y=2500-----(ii)}$

In eq (i) multiplying by 5 and in eq (ii) by 6:-]

$\tt{\implies 30x-25y=12500}$

$\tt{\implies 30x-24y=15000}$

By solving we get here:-]

$\tt{\implies -y=-2500}$

$\tt{\implies y=2500}$

Putting the value of y in eq (I)

$\tt{\implies 6x-5y=2500}$

$\tt{\implies 6x-5*2500=2500}$

$\tt{\implies 6x-12500=2500}$

$\tt{\implies 6x=2500+12500}$

$\tt{\implies 6x=15000}$

$\tt{\implies x=2500}$

$\sf\large{Hence,}$

$\tt{\implies Monthly\: income\:_{(Amit)}=6x}$

$\tt{\implies Monthly\: income\:_{(Amit)}=6*2500}$

$\bf{\implies Monthly\: income\:_{(Amit)}=Rs.15000}$

$\tt{\implies Monthly\: income\:_{(Atul)}=5x}$

$\tt{\implies Monthly\: income\:_{(Atul)}=5*2500}$

$\bf{\implies Monthly\: income\:_{(Atul)}=Rs.12500}$
