The perimeter of a rectangle is 40m and one side of it is 5m. What is the length of the other side using an equation?
Perimeter of the rectangle =2(l+ b)=40m
If one of its side b=5, then l = (40/2)-5
= 20–5
= 15 m Therefore
Length= 15 cm
Breadth =5 cm
Answer:

Step-by-step explanation:
Surface area for a sphere is
π
,
Diameter is 10, so radius is 5. Radius is half of diameter.
A=4×π×
=
Nearest tenth: 
Therefore, it is 
Good luck!
Tan 32 = f/18
f = 18 × tan 32
= 11.25
= 11 ( to 2 sf)
