Landon used a semicircle, a rectangle, and a right triangle, to form a figure below. which is the best estimate of he area of the figure in square centimeters?

The area of the figure is 38.28cm².

The area of the shape is the sum of the area of the semicircle, a rectangle, and a right triangle.

Area of a semicircle = r²

x 3.14 x (4/2)²  = 6.28 cm²

Area of the rectangle = length x width

6 x 4 = 24 cm²

Area of the right triangle = x base x height

x (10 - 6) x 4 = 8cm²

Sum of the areas = 8 + 24 + 6.28 = 38.28cm²

The best estimate of he area of the figure is

Step-by-step explanation:

we know that

The area of the figure is equal to the area of a semicircle plus the area of rectangle plus the area of a right triangle

so

we have

Semicircle

----> the radius is half the diameter

Rectangle

Triangle

substitute the values

step-by-step explanation:

the answer is 128

answer is c
