Answer:
<h3>The length is 35cm</h3><h3>The width is 5cm</h3><h3 />
Step-by-step explanation:
Area of a rectangle = l × w
where
l is the length
w is the width
The length is seven times the width is written as
l = 7w
Area of the rectangle = 175 cm²
7w × w = 175
7w² = 175
Divide both sides by 7
w² = 25
Find the square root of both sides
w = √25
w = 5cm
But l = 7w
l = 7(5)
l = 35cm
The length is 35cm
The width is 5cm
Hope this helps you.

Step-by-step explanation:
Formula for the volume of cone is 
Where r= radius of the cone
h = height of the cone
The value of pi is 3.14
Given volume of larger cone is 131 cm^3
Volume of larger cone =
131 = 
Solve for h
131 = 26.1667 *h
So h= 5 cm
The height of bigger cone = 5cm
Now we find the volume of smaller cone
Two cones similar so the sides are in proportional
Height of smaller cone = 2cm
volume of smaller cone = 
= 8.38cm^3
Answer: 952 ft squared
Step-by-step explanation:
Surface area, is just the area of all the faces added together.
So, the sides we need to find are measuring:
Triangle side: 10 x 8
Triangle Face; 10 x 8
Square Face: 10 x 10
Square Face: 10 x 10
Rectangular Face: 14 x 10
Rectangular Face: 14 x 10
Bottom Rectangular face: 14 x 10
Side of the Triangular prism: 9 x 14
Side of the Triangular prism: 9 x 14
Because the triangle face has two of them, we only have to do one as opposed to dividing the same face twice.
So, we have a side of 80.
From here, it is just multiplication.
80 + 100 + 100 + 140 + 140 + 140 + 126 + 126 = 952 ft
