The ratio of the length of two rectangles is 24 : 23 and the breadth of the two rectangles is 18 : 17. If the perimeter of the second rectangle is 160 cm and the length of the second rectangle is 12 cm more than its breadth, then find the area of the first rectangle ?
The area of a rectangular field is 15 times the sum of its length and breadth. If the length of that field is 40 m, then what is the breadth of that field?
Half of the perimeter of a rectangle is 45 cm. If the length of a rectangle is 5 cm more than its breadth, then what is the area of the rectangle?
A path of uniform width of 1m inside the rectangular park of 20m and 15m are made. Find the area of a path.
The area of a square and a rectangle is equal. The length of the rectangle is 6 cm more than the side of the square and breadth is 4 cm less than the side of the square. What is the perimeter of the rectangle?
Length of the rectangle is x cm and the diagonal of the rectangle is (x + 1) cm. Then the breadth of the rectangle is (x - 7) cm. Find the perimeter of the rectangle. (x ≠ 4)
The length of a rectangle is of the radius of a circle. The radius of the circle is equal to the side of a square whose area is 4900 m2. What is the area (in m2) of the rectangle, if its breadth is 20 m?
A rectangular lawn whose length is twice of its breadth is extended by having four semi-circular portions on its sides. What is the total cost (in Rs.) of levelling the entire lawn at the rate of Rs. 100 per square metre, if the smaller side of the rectangular lawn is 12 m? (Take π = 3.14)
A park is in the shape of a rectangle. Its length and breadth are 240 m and 100 m, respectively. At the centre of the park. there is a circular lawn. The area of the park, excluding the lawn is 3904 m2. What is the perimeter (in m) of the lawn? (use π = 3.14 )
The area of a square and a rectangle are equal. The length of the rectangle is greater than the side of square by 9 cm and its breadth is less than the side of square by 6 cm. What will be the perimeter of the rectangle?
The area of a field in the shape of a regular hexagon is 3750√3 m2. What will be the cost (in Rs.) of putting fence around it at Rs. 29 per meter?
The length of rectangle is increased by 10% and the breadth is increased by 25%. What is the percentage change in its area?
A hall 25 metres long and 15 metres broad is surrounded by a verandah of uniform width of 3.5 metres. The cost of flooring the verandah, at 27.50 per square metre is
The length and breadth of a rectangular field are in the ratio of 3 : 2. If the perimeter of the field is 80m, its breadth (in metres) is :

The breadth of a rectangular hall is three-fourth of its length. If the area of the floor is 768 sq. m., then the difference between the length and breadth of the hall is:
If the perimeters of a rectangle and a square are equal and the ratio of two adjacent sides of the rectangle is 1 : 2 then the ratio of area of the rectangle and that of the square is
If the area of a triangle with base 12 cm is equal to the area of a square with side 12 cm, the altitude of the triangle will be
The areas of a square and a rectangle are equal. The length of the rectangle is greater than the length of any side of the square by 5 cm and the breadth is less by 3 cm. Find the perimeter of the rectangle.
