This figure consists of a rectangle and semicircle. what is the perimeter of this figure? use 3.14 for pi. 60.84 m 72.84 m 79.68 m 98.52 m a shape made up of a rectangle of the left and a semicircle on the right. the rectangle has a width of 15 meters and a height of 12 meters.

The perimeter of the figure is

Step-by-step explanation:

we know that

The perimeter of the figure is equal to the perimeter of a rectangle plus the circumference of a semicircle minus the diameter of the circle

so

Find the perimeter of the rectangle

The perimeter of the rectangle is equal to

substitute the values

Find the circumference of a semicircle

The circumference of a semicircle is equal to

substitute the value of r

-----> the radius is half the diameter

Find the perimeter of the figure

the correct answer is $7.38

step-by-step explanation:

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.
