Answer:
32
Step-by-step explanation:
The given fig. has 2 similar rectangles and 1 square
Length of rectangle= 7 units
Breadth of rectangle=2 units
Perimeter of a rectangle = 2(l+b) =2(7+2)= 18 units
For two rectangles = 2 × 18= 36 units
Now perimeter of square = 4a
Since two sides are adjacent to the rectangles we minus this two sides (side of square is 2 units)
36-(4a-2a)
36-(4a-2a)=36-2a
36-(4a-2a)=36-2a =36-2×2
36-(4a-2a)=36-2a =36-2×2=32units
