The length and breadth of a rectangle are in the ratio 3 : 1. What is the perimeter if the area is 27 sq. meters?
What is the area of the largest circle that can fit completely inside a square of side 18 meters?
Two concentric circles of radii 18 and 16 cm are drawn on a paper. What is the area of the portion that is inside the outer circle but outside the inner circle?
The length and breadth of a rectangle are respectively increased by 13% and 10%. What is the % increase in the area?
The difference between the length and breadth of a rectangle is 30 m. What is the area if the perimeter is 92 meters?
304 sq. meters.
306 sq. meters.
302 sq. meters.
308 sq. meters.
If L and B are the length and breadth of the rectangle, then L - B = 30 and 2(L + B) = 92. Solving, we get L = 38 and B = 8, so the area is 38 × 8 = 304 sq. m. TIP: Sometimes long multiplications can be avoided by looking at the units place of the given options.
