If the ratio of length to breadth of a rectangle is 5:3 and its perimeter is 144m . Find the length and breadth of rectangle

Answer»

Given :

Ratio of length to breadth of a RECTANGLE is 5:3.
Perimeter of Rectangle = 144m

To Find :

Length and Breadth of Rectangle.

Solution :

$\longmapsto\tt{Let\:Length\:be=5x}$

$\longmapsto\tt{Let\:Breadth\:be=3x}$

$\longmapsto\tt{Perimeter=144m}$

Using Formula :

$\longmapsto\tt\boxed{Perimeter\:of\:Rectangle=2(l+b)}$

Putting Values :

$\longmapsto\tt{144=2(5x+3x)}$

$\longmapsto\tt{\cancel\dfrac{144}{2}=5x+3x}$

$\longmapsto\tt{72=8x}$

$\longmapsto\tt{x=\cancel\dfrac{72}{8}}$

$\longmapsto\tt\bold{x=9}$

So , The value of x is 9..

Therefore :

$\longmapsto\tt{Length=5(9)}$

$\longmapsto\tt\bold{45m}$

$\longmapsto\tt{Breadth=3(9)}$

$\longmapsto\tt\bold{27m}$

_______________________

VERIFICATION :

$\longmapsto\tt{144=2(l+b)}$

$\longmapsto\tt{144=2(45+27)}$

$\longmapsto\tt{144=2(72)}$

$\longmapsto\tt\bold{144=144}$

The AREA of a circle = πr² = 3.14 (APPROX) x 22.5² = 3.14 x 506.25 = 1589.625 cm² The area of the metal sheet = 45 x 48 cm² = 2160 cm² The area of the remaining portion of metal sheet = area of sheet - area of circle = 2160 - 1589.625 cm² = 570.375 cm² Hope it helps!!

29.

From a rectangular metal sheet of sides 45cm and 48cm, the largest possible circular sheet is cut off. Find the area of the remaining portion of metal sheet.?

Answer»

Answer:

570.375 cm²

Step-by-step explanation:

The circle's radius will be the half of the SMALLER SIDE, which is 45 cm ( also the diameter).

The radius = 22.5 cm.

The AREA of a circle = πr²

= 3.14 (APPROX) x 22.5²

= 3.14 x 506.25

= 1589.625 cm²

The area of the metal sheet = 45 x 48 cm²

= 2160 cm²

The area of the remaining portion of metal sheet

= area of sheet - area of circle

= 2160 - 1589.625 cm²

= 570.375 cm²

Hope it helps!!

Hy friends solve this question

Answer»

Solution :

For solving these KIND of questions,First of all we've to break the numbers in their simple Form.

We have :

$\longmapsto \sf \: 3 \sqrt{<klux>12</klux>} \times 6 \sqrt{4}$

We can write :

$\star \sf \: \sqrt{12} \: as \: \sqrt{2 \times 2 \times 3} = 2 \sqrt{3}$

$\star \sf \: \sqrt{4} \: as \: \sqrt{2 \times 2} = 2$

Put the values :

$\longmapsto \sf \: 3(2 \sqrt{3)} \times 6(2)$

$\longmapsto \sf \: 6 \sqrt{3} \times 12$

Now,Multiply 12 and 6 and keep √3 APART

Solve the question pls

Answer»

Solution :

For solving these KIND of QUESTIONS,you need to BREAK them in their SIMPLE Form

We have :

$\longmapsto \sf \: 5 \sqrt{8} + 2 \sqrt{32} - 2 \sqrt{2}$

We can write :

$\star \sf \: \sqrt{8} \: as \: \sqrt{2 \times 2 \times 2} = 2 \sqrt{2}$

$\star \sf \: \sqrt{32} \: as \: \sqrt{2 \times 2 \times 2 \times 2 \times 2} = 4\sqrt{2}$

Let's put the value :

$\longmapsto \sf \: 5(2 \sqrt{2} ) + 2(4 \sqrt{2} ) - 2 \sqrt{2}$

$\longmapsto \sf \: 10\sqrt{2} + 8 \sqrt{2} - 2 \sqrt{2}$

Here,√2 is common. Let's TAKE it out

$\longmapsto \sf \: 10 + 8 - 2 \sqrt{2}$

Now,Solve the left numbers.

$\longmapsto \sf \: 18 - 2 \sqrt{2}$

$\longmapsto \large \boxed{ \purple{ \sf \: 16 \sqrt{2} }}$

Hence,Required value is 16√2
