If perimeter of a rectangle is 14 cm and length is 5 cm, then find the area of the rectangle.
The correct option is A 10 cm2
Length of the rectangle = 5 cm
Perimeter = 14 cm
We know that,
Perimeter of rectangle = 2(length + breadth)
14 = 2(5 + breadth)
7 = (5 + breadth)
So, breadth = 2 cm
Area of rectangle = length×breadth
= 10 cm2
Therefore, area of the rectangle is 10 cm2.
