36 unit squares are joined to form a rectangle with the least perimeter. The perimeter of the rectangle is
(a) 12 units (b) 26 units (c) 24 units (d) 36 units
Answer:
(b) 26 units
From the question it is given that, area of rectangle = 36 units2
36 can be written as = 6 × 6
= (2 × 3) × (2 × 3)
= 22 × 32
= 4 × 9
Then, the sides of the rectangle are 4 cm and 9 cm.
We know that, perimeter of the rectangle = 2 (length + breadth)
= 2 (4 + 9)
= 2 (13)
= 26 units
