Answer 1

ANSWER

A=16

EXPLANATION

The radius of the circle is r=4 units.

The area of a triangle is

$\frac{1}{2} bh$

Both the height and the base of the triangle are radii, which is 4 units.

The area of the two isosceles right triangle is

$2(\frac{1}{2} \times 4 \times 4) = 16$

Answer 2

Answer:

Area of combined triangle = 2 * 8 = 16 square units

Step-by-step explanation:

Points to remember

Area of triangle = bh/2

b - Base and h - Height

From the figure we can see that a circle and two right angled triangles.

To find the combined area of triangles

Here base and height of two triangles is equals to radius of circle

Therefore b = 4 and h = 4

Area of one triangle = bh/2

 = (4 * 4)/2 = 8 square units

Area of combined triangle = 2 * 8 = 16 square units
