Answer:
- Length of a rectangle is 4, breadth 0 and perimeter is 8meters.
- No, Raju said that the area of the rectangle is 24sq.m is wrong.
Step-by-step explanation:
Given: length = x + 2
breadth = x - 2
Perimeter of rectangle = 8 m
Perimeter of rectangle = 2 (length + breadth)
2 (x + 2 + x - 2) =8
2x = 8/2
2x = 4
x = 2
So, length = 2 + 2 = 4 cm
And breadth = 2 -2 = 0 cm
The area of rectangle = length × breadth
= 4 × 0
= 0
No, we do not agree because the area is zero because breadth is zero.
