Answer:

$40.40

Step-by-step explanation:

1. Round each decimal to the nearest tenth. Keep in mind that the sum is the answer to an addition problem.

$4.28 = $4.30

$21.35 = $21.40

$14.65 = $14.70

2. Now, all we have to do is add up the three decimals to find the answer.

$21.40 + $14.70 + $4.30 = $40.40

Conclusion: Your answer is $40.40

Vladimir79 [104]

Answer:

38.13m²

Step-by-step explanation:

We find the area of ;

Rectangule and semicircle

Area of rectangle :

Length * width

Length = 8m ; width = 3m

Area = 8 * 3 = 24m²

Area of semicircle = 1/2 πr²

Radius, r = 3m

A = 1/2 * 3.14 * 3²

A = 1/2 * 3.14 * 9

A = 14.13 m²

Area of patio :

(24 + 14.13)m²

= 38.13m²
