Answer:
5.14
Step-by-step explanation:
The way i solved this was i found the length of the line by taking the 2 (Width and also "A") and the 7 (The height and also "B"), squared both of them and added them together. Then found the square root. Sense i suck at explaining things this is what the equation should have looked like. 
÷ 2. (Side wait for someone else to answer because i'm 70% sure this is right.
Problem:
The area of the patio of a relative's house is 20 square meters.
The width of the patio is 2 meters.
What is the length of the patio?
Solution:
The area is:
A = (w) * (l)
Where,
w: width
l: long
Clearing l we have:
l = A / w
Substituting values:
l = 20/2
l = 10 meters
Answer: No
Step-by-step explanation:
2.7 + 3.5 is not greater than 9.8.
Answer:
234 mm²
Step-by-step explanation:
area of each side = L x W
(15 x 3 x 2) + (15 x 4 x 2) +(3 x 4 x 2) = 234 mm²
The answer is 3
B+4=7
B=7-4
B=3
