multiply the length by the width to find the area
To find the area of the arrow formed in a 2 by 2 square, we first need to determine the area of the square, which is 2 x 2 = 4 square units. The arrow consists of two right triangles, each with a base of 1 unit and a height of 1 unit. The area of one right triangle is 1/2 x base x height = 1/2 x 1 x 1 = 0.5 square units. Since there are two right triangles in the arrow, the total area of the arrow is 0.5 + 0.5 = 1 square unit.

Because you will be using the number pi to find the area of the circle, some rounding will be required.
By using the formula: area of circle = pi*radius2
