Question

If perimeter of the rectangular top of a table is 12 m and length is 4 m, then find the area of the rectangular top.

• A. $8m^2$
• B. $9m^2$
• C. $10m^2$
• D. $11m^2$

Answer 1

The correct option is A $8m^2$

Given,
Length of the rectangle = 4 m
Perimeter = 12 m

We know that,
Perimeter of rectangle
= 2(length + breadth)
12 = 2(4 + breadth)
6 = (4 + breadth)

So, breadth = 2 m

Area of rectangle = length$\times$breadth
= 4$\times$2
= 8 $m^2$

Therefore, area of the rectangular top is $8m^2$.
