Find the area of the composite figure.

Bad White [126]

Answer:

Area = 139.27 m²

Step-by-step explanation:

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

= (L*W) + ½(πr²)

L = 10 m

W = 10 m

r = ½ of 10 = 5 m

Plug in the values

Area = (10*10) + ½(π*5²)

Area = 100 + 39.27

Area = 139.27 m²

Luden [163]

we know that

1) Lily swims a $100$ -meter race

2) She swims the first half in $27.8$ seconds

3) She swims the second half in $30.12$ seconds

To find the total time to swim the whole race sum the time in the first half plus the time in second half

$(27.8+30.12)=57.92\ seconds$

therefore

<u>the answer is</u>

$57.92\ seconds$
