The unlike terms in perimeters of following figures are___________ and __________. Fill in the blanks to make the statement true.
Solution:
Given, the unlike terms in perimeters of the given figures are___________ and __________.
We have to fill in the blanks to make the statement true.
Fig(i) represents a rectangle.
Perimeter of rectangle = 2(length + breadth)
Length = 2x
Breadth = y
Perimeter = 2(2x + y) = 4x + 2y —-------------- (1)
Fig(ii) represents a parallelogram.
Perimeter of parallelogram = 2(length + breadth)
Length = x
Breadth = y²
Perimeter = 2(x + y²) = 2x + 2y² —-------------- (2)
From (1) and (2),
The unlike terms are 2y and 2y².
Therefore, the unlike terms are 2y and 2y².
