Question

AB||DC and DA_|_AB .If DC=7cm , z's BC=10cm,AB=13cm and CL_|_AB,the area of trapezium ABCD is​

Answer 1

Answer:

The Area is 80cm^2

Step-by-step explanation:

Your diagram is wrong.

Construct CE _|_ to AB.

In rect< AECD, AE=7. {Opposite sides}

In ∆CEB, BE=6. {13-7}

CE=√((10^2)-(6^2))

CE=height=8cm

Area(trapezoid)=(h/2)*(Sum of || sides)

Area=8*0.5*(13+7)

Area=4*20

Area=80cm^2
