Answer:
H = 12cm
b
I hope I was able to help
105 m = 2.5 h
x miles = 1 hour
You cross multiply since it's a proportion:
2.5 * x
105 * 1
=
2.5x = 105
Then you divide everything by 2.5
The answer is 42
Answer:
<h2>S.A. = 234 mm²</h2>
Step-by-step explanation:
The formula of a surface area of a rectangular prism:

l - length
w - width
h - height
We have l = 15 mm, w = 3 mm, h = 4 mm. Substitute:

length is 8m
Width is 6.5m
<u>Explanation:</u>
Let, width = b
So, length = 2b-5
area = 52
We know,
area of rectangle = length X width
So,
= 
On solving the above equation, we get
Width, b = 6.5m
length, l = 8m
