Step-by-step explanation:

The solution is Option A.

The area of the token not covered by the triangles is 25.76 cm²

What is a Triangle?

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

Given data ,

Let the area of the token not covered by triangles be A

Let the area of the triangle be T

Now , the height of the triangle h = 1 cm

The base of the triangle b = 1 cm

The area of the triangle = 1/2 x l x b

Substituting the values in the equation , we get

Area of the triangle T = 1/2 cm²

The number of triangles = 5

The area of 5 triangles = 5 x Area of the triangle

The area of 5 triangles = 5/2 cm²

The area of 5 triangles = 2.5 cm²

Now , the radius of the circle r = 3 cm

The area of the circle = πr²

Substituting the values in the equation , we get

Area of the circle = 3.14 x 3 x 3

Area of the circle = 28.26 cm²

Now , the area of the token not covered by triangles
A = Area of the circle - area of 5 triangles

Substituting the values in the equation , we get

The area of the token not covered by triangles A = 28.26 - 2.5

The area of the token not covered by triangles A = 25.76 cm²

Therefore , the value of A is 25.76 cm²

Hence , the area of the token without triangles is 25.76 cm²
