The area of a field in the shape of a trapezium measures 1440 m2. The perpendicular distance between its parallel sides is 24 m. If the ratio of the parallel sides is 5 : 3, the length of the longer parallel side is :
The length and breadth of a rectangular field are in the ratio 7 : 4. A path 4 m wide running all around outside has an area of 416m2. The breadth (in m) of the field is
A path of uniform width runs round the inside of a rectangular field 38 m long and 32 m wide. If the path occupies 600m2 , then the width of the path is
The area of a circle is increased by 22 cm2 when its radius is increased by 1 cm. The original radius of the circle is
The circumference of a circle is 11 cm and the angle of a sector of the circle is 60°. The area of the sector is
