Question

Find the area of the trapezium ABCD as given in the figure in which ADCE is a rectangle.

• A. $55c{m}^2$
• B. $40c{m}^2$
• C. $45c{m}^2$
• D. $35c{m}^2$

Answer 1

The correct option is C $45c{m}^2$


Area of trapezium ABCD
= Area of triangle BEC + Area of rectangle AECD
= ($\frac{1}{2}\times CE\times BE)+(CD\times CE)$
= $(\frac{1}{2}\times 10\times 3)+(3\times 10)$
= $15+30$
= $45c{m}^2$
