Question

Find the area of a trapezium whose parallel sides are 57 cm and 39 cm, and the distance between them is 28 cm.

• A. $1344c{m}^2$
• B. $1244c{m}^2$
• C. $1144c{m}^2$
• D. $1044c{m}^2$

Answer 1

The correct option is A $1344c{m}^2$

Let ‘a’ and ‘b’ be the parallel sides of the trapezium and ‘h’ be the height of the trapezium

Area of trapezium
$=\frac{1}{2}\times \left(Sumoftheparallelsides\right)\times height$

$=\frac{1}{2}\times (57+39)\times 28=1344c{m}^2$
