Answer:
The breadth of the rectangle is 10 units.
Step by Step Explanation:
•The side of the square is 15units.
•So its perimeter will be
= 4 × side
= 4× 15
= 60 units.
•It is given that the perimeter of square is equal to the perimeter of the rectangle.
•So, the perimeter of the rectangle is 60 units.
•Perimeter of a rectangle = (2length + 2 breadth)
60= [ (2×20) + (2×breadth) ]
60 = 40 + 2 breadth
60-40 = 2breadth
20 = 2 breadth
breadth = 10 units.
Answer- The breadth of the rectangle is 10 units.
