The difference between the length and breadth of a rectangle is 2 m. What is the area if the perimeter is 8 meters?
3 sq. meters.
5 sq. meters.
9 sq. meters.
7 sq. meters.
If L and B are the length and breadth of the rectangle, then L - B = 2 and 2(L + B) = 8. Solving, we get L = 3 and B = 1, so the area is 3 × 1 = 3 sq. m. TIP: Sometimes long multiplications can be avoided by looking at the units place of the given options.
