Answer:

The width of the frame must be 12 inches (15in by 12in)

Step-by-step explanation:

Given

See attachment for painting and frame

Required

Determine the dimension of the frame

To do this, we make use of the following scale ratio.

Scale = Length : Width

For the painting,

Scale = 20: 16

For the frame,

Scale = 15: w

Since she wants to maintain the same ratio; both scale must be the same.

i.e.

15 : w = 20 : 16

Express as fraction

\frac{w}{15} = \frac{16}{20}

\frac{w}{15} = 0.8

Make w the subject

w = 15 * 0.8

w = 12

<em>The width of the frame must be 12 inches i.e. 15in by 12in frame</em>

Answer: 659 13/18 yd^2 or 659.7yd^2                ^ =squared

Step-by-step explanation:

This is the answer because you have 6 sides of this prism. That means 3 sides are parallel to the sides across from them. So, 12 1/2 yd by 8 1/3 yd is 104 1/6, then multiply by 2. That equals 208 1/3. Then, 10 5/6 yd by 8 1/3 yd is 90 5/18. then times by 2. That equals 180 5/9. Next, 10 5/6yd by 12 1/2 is 135 and 5/12. then times by 2 and that is 270 5/6yd.

add 208 1/3 + 180 5/9 + 270 5/6

659 13/18 yd^2
