Solve for r.
You want to get r by itself on one side on the equal sign.
bh + hr = 25
Subtract bh from both sides.
hr = 25 - bh
Divide h on both sides.
r = 25 - bh / h
The two h's cancel each other out.
r = 25 - b

Answer:
Perimeter of the figure = 24 m.
Step-by-step explanation:
The given figure is a square of side 6 m in which a rectangle of length 4 m and width 2 m is cut at the corner.
Therefore, the missing sides are 6-4 = 2 m and 6-2 = 4 m.
Hence, the perimeter of the figure = 6 + 6 + 2 + 2 + 4 + 4 = 24 m.
 
        
             
        
        
        
Answer:
Rectangle 
Step-by-step explanation:
The shape is of a rectangle who has got two pairs of opposite sides that are parallel and two pairs of sides that are of equal length of each other with all  the four right angles that makes up total angle of 360 degrees in total. It can be acquired that the area which is equal to length multiply by breadth. 
Calculation, 
A length of the rectangle is equal to each other, 
Assuming it to be 3cm, 
Breadth of it is equal to each other, 
Assuming that to be 2cm,
Length x Breadth = Area 
3 x 2 = 6cm to the power 2.
