Answer:
Length, l = 10 m, breadth = 8 m
Step-by-step explanation:
Let l be the length and b be the width of the rectangle.
The area of a rectangle is given by :
A = lb
80 = lb ...(1)
The perimeter of a rectangle is given by :
P = 2(l+b)
36 = 2(l+b)
18 = (l+b) ....(2)
We need to solve equation (1) and (2). On solving we get :
l = 10, b = 8
So, the dimensions of the shop is 10 m and 8 m.
The missing value is 6 so 2/5 = 6/15
If you want to find out the average of something.
Answer:
Step-by-step explanation:
P≥300
300≤P
P=2(L+W)
300≤2(L+W)
L=3
W=x+5
300≤2(3+x+5)
300≤2(8+x)
divide both sides by 2
150≤8+x
minus 8 both sides
142≤x
x is at least 142
width is at least 147
