1. $9549.6
Fist we find the area off all bedrooms.
Master Bedroom: 14*14 = 196
Bedroom2: 11*12 =132
Bedroom3: 12*11 = 132
Then add them together:
132+132+196=460
Now each yard costs $20.76, and we have 460 yards to cover. So time them together:
20.76*460 = $8549.6
2. You got it right! Keep it up!
3. 510m²
We can divide it into two different figures, a rectangle and a triangle.
Then the rectangle will be 13 by 30.
So the area of the rectangle is 390.
Then we have the total height, and we have the height of rectangle. We do 21-13 because we already have the area of the rectangle.
21-13=8
Then we have the base of the triangle and the height, then we do:
1/2 * 8 * 30 = 120
In the end, we add the rectangle and triangle together:
120+ 390= 510
4. You have it perfect!
5a. 78
Add all sides together...
32.5+ 19.5+ 26= 78
5b. 253.5
[tex] \frac{1}{2}bh=a [/tex]
So 1/2* 19.5*26.0 =253.5
