What is the area of this figure?
Dima020 [189]

Answer:

220.5 \:  {yd}^{2}

Step-by-step explanation:

Area of the figure = Area of the arc with radius 10 yd and central angle 90° + Area of rectangle with dimensions (10 + 5 - 3 = 12) 12 yd and (7 + 6 - 4 = 9) 9 yd + Area of square with dimension 4yd + Area of rectangle with dimensions 3 yd by 2 yd + Area of triangle with base 3 yd and height (5 + 3 = 8) 8 yd.

=  \frac{90 \degree}{360 \degree}  \times 3.14 {(10)}^{2}  + 12 \times 9 +  {4}^{2} \\ + 3 \times 2 +  \frac{1}{2}  \times 3 \times 8 \\  \\  =  \frac{1}{4}  \times 314 + 108 + 16 + 6 + 12 \\  \\  = 78.5 + 142 \\  \\  = 220.5 \:  {yd}^{2}

would you rather have cheez its to cover a rectangle with a length of 9 and a perimeter of 22 or a length of 5 and a perimeter o
Sonbull [250]

Answer:

A length of 5 and a perimeter of 20

Step-by-step explanation:

Personally, I'm lactose intolerant so I wouldn't take any Cheez-Its, but oh well.

Everyone wants the most Cheez-its, right? So we need to find the rectangle with the greatest area.

Let's look at the first one, a rectangle with a length of 9 and a perimeter of 22.

The perimeter of a rectangle can be expressed as 2l+2w, where l is the length and w is the width.

We know the length and area, so let's solve for w (the width).

2\cdot9+2w=22\\\\18+2w=22\\\\2w=4\\\\w=2

So the width is 2. The area of a rectangle is the length times the width.

9\cdot2=18

So the first rectangle has an area of 18.

Using the same concept for the second statement, a length of 5 and a perimeter of 20, we can find the area.

2l+2w=20\\\\2\cdot5+2w=20\\\\10+2w=20\\\\2w=10\\\\w=5\\\\5\cdot5=25

So the area of the second one is 25.

The greatest area is 25, so you'd want this one.

Hope this helped!
