Answer:
Step-by-step explanation:
Given triangles are similar, so we setup a proportion
(140-x)/81 = x/9
solving gives x = 14
AC = 140-x = 140-14 = 126
Given that Roger is building a storage shed with wood blocks that are in the shape of cubic prisms.
cube is basicallye a box which is made of squares. That is all the sides (lenght, width and height) are equal.
Now we have to determine, Can he build a shed that is twice as high as it is wide.
that means if width is 1 then height should be twice which is 2.
yes that is possible if we put one cubical prism over another cubical prism. then height of shed due to two prism will be twice than the width.
Hence correct choice should be "A. Yes. For every block of width, he could build two blocks high."

<h3><u>Givєn</u> :</h3>
- Radius of the tent,r = 3.5 m
- Height of the tent, h = 8.4 m
<h3><u>To Find</u> :</h3>
- length of the cloth required.
<h3><u>Solution</u> :</h3>
According to the question,
Slant height, l = 
curved surface area = 
i.e., Area of the cloth is 101.11m²
Now, length of the cloth required = 
Answer:
C :She is incorrect because she should have squared each leg length and then found the sum
