In the trapezium DICE,
DI = 6 cm
IC = ED = 5 cm
CE = 3 cm and DI || EC
Construction:
Steps:
Draw a line segment DI = 6 cm.
Mark a point M on DI such that DM = 3cm
With D and I as centres, draw arcs of radii 5 cm each Let them cut at C. Join MC and IC.
Draw CX parallel to DI
With D as centre, draw an arc of radius 5 cm. Let it cut CX at E
Join DE. DICE is the required trapezium.
Calculation of area:
Area of the trapezium DICE = 12 x h x (a + b) sq. units
= 12 x 3.8 x (6 + 3) sq. units
= 12 x 3.8 x 9
= 17.1 sq. cm
its the answer..
