Question

find the perimeter of the given figure in which an equilateral triangle is attached to a semi circle having radius 4.9 cm.​

Answer 1

Answer:

Explanation:

To find the perimeter of an equilateral triangle given its area, we must first find the length of the sides. This can be done by using the equation of the area of an equilateral triangle:

where a is the side of the triangle.

Because the sides of the equilateral triangle are equal, the perimeter is equal to 3a.

Step-by-step explanation:

Correct answer:

24.1

Explanation:

To find the perimeter of an equilateral triangle given its area, we must first find the length of the sides. This can be done by using the equation of the area of an equilateral triangle:

Area=a23–√4

where a is the side of the triangle.

Because the sides of the equilateral triangle are equal, the perimeter is equal to 3a.
