Answer:
a) length = 3 and width = 6
Area of the rectangle = 3 × 6 = 18 cm²
b) length = 7 and width = 2
Area of the rectangle = 7 × 2 = 14 cm²
c) length = 5 and width = 4
Area of the rectangle = 5× 4 = 20 cm²
Step-by-step explanation:
Step(i):-
Given perimeter of the paper = 18 cm
we know that the paper has a rectangle shape
The perimeter of the rectangle = 18 cm
2( l + w ) = 18
a)
we choose length = 3 and width = 6
The perimeter of the rectangle = 2( 3+6) = 18 cm
Area of the rectangle = 3 × 6 = 18 cm²
b)
we choose length = 7 and width = 2
The perimeter of the rectangle = 2( 7+2) = 18 cm
Area of the rectangle = 7 × 2 = 14 cm²
c)
we choose length = 5 and width = 4
The perimeter of the rectangle = 2( 5+4) = 18 cm
Area of the rectangle = 5× 4 = 20 cm²
