The figure shows the cross-section of the interior of thermos flask . The top part is a trapezium , the middle part is a rectangle and the bottom part is a semicircle if CE = 20 cm , BC = 25 cm , AB = GF = 13 cm , AG = 10 cm and AN = 12 cm , the find : The perimeter of the cross-section

How many bricks, each of size 25cmxx13.5cmxx6cm , will be required to build a wall 8 m long, 5.4 m high and 33 cm thick?"

The parallel sides of a trapezium are 25cm and 13cm; its nonparallel sides are equal,each being 10cm, find the area of the trapezium.

The area of trapezium field whose parallel sides are 25 cm, 13 cm and other sides are 15 cm and 15 cm.

7.Which of the following can be the sides of a right-angled triangle? a)0.5 cm,1.2 cm and 1.3 cm b) 5.0 cm , 5.25 cm and 7.25 cm

In a triangle, the sides are given as 11 cm, 12 cm and 13 cm. The length of the altitude is 10.25 cm corresponding to the side having 12 cm.

The distance between the centres of two circles of radius 2.5 cm each is 13 cm. The length (in cm ) of a transverse common tangent is
