If length of three sides of a trapezium other than base are equal to 10 cm, then find the area of the trapezium when it is maximum.

Question 1

Question 2

The required trapezium is as given in figure. Draw perpendiculars DP and CQ on AB. Let AP = x cm. Note that △APD ≅ △BQC . Therefore, QB = x cm. Also, by Pythagoras theorem DP = QC = √100 - x2 .

Let A be the area of the trapezium.
