What is the area of this composite shape?

Enter your answer in the box.

_in²

The area of the composite figure is

Explanation:

From the given figure, we can see that the area of the composite figure = area of the rectangle + area of the triangle.

Area of the rectangle :

The formula is given by

where and

Substituting, we have,

Thus, the area of the rectangle =

Area of the triangle :

The formula is given by

where

and

Substituting, we have,

Thus, the area of the triangle =

Area of the composite figure = Area of the rectangle + area of the triangle

Area of the composite figure =

Thus, the area of the composite figure is

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
