Question

please please tell me answer​

Answer 1

Answer:

• Given:

$\textsf{Length of one side of the equilateral triangle:}$

$=8\frac{1}{2}cm$

$\textsf{Total sides of the equilateral triangle:}$

$=\:3\:sides$

• To find:

$\textsf{To find the 1/4 th part of the perimeter of the}$$\textsf{equilateral triangle. }$

• Concept:

Each side of the equilateral triangle is same .

To find the 1/4 th part first find the perimeter of the equilateral triangle.

Then , find the 1/4 th part of the perimeter of the equilateral triangle by dividing the perimeter to 1/4 th .

• Taken:

To find the perimeter:

$P=S×3$

Where,

P = Perimeter of the equilateral triangle

S = Length of one side of the equilateral triangle

• Solution:

Perimeter:

$Taken,P=S×3$

$\mapsto{P=8\frac{1}{2}×3}$

$\mapsto{P=\frac{17}{2}×3}$

$\mapsto{P=\frac{51}{2}cm}$

Now , find the 1/4 th part of the perimeter:

$Taken,\frac{51}{2}÷\frac{1}{4}$

$\mapsto{\frac{51}{2}÷\frac{1}{4}}$

$\mapsto{\frac{51}{2}×\frac{4}{1}}$

$\mapsto{102cm}$

• Answer:

$\textsf{So , the 1/4 th part of the equilateral triangle is}$$\textsf{102 cm}$

• Additional information:

To find the area of the triangle:

$A=\frac{H×B}{2}$

Where,

A = Area of the triangle

H = Height of the triangle

B = Base of the triangle

To find the perimeter of the square:

$P=S×4$

Where,

P = Perimeter of the square

S = One side of the square

To find the area of the square:

$AS=S×S$

Where,

AS = Area of the square

S = One side of the square
