Question

(b)The perimeter of a trapezium is 52cm. If its non–parallel sides are 10cm each and its altitude is 8cm,

find the area of the trapezium​

Answer 1

Answer:

primeter of a trapezium:52cm

non-parallel sides:10cm

altitude is 8cm

Step-by-step explanation:

The area of trapezium is 4652

is the trapezium

Answer 2

Answer:

Let the measure of the parallel sides be and and b respectively.

Perimeter = 52cm

⇒ a+b+10+10=52

⇒ a+b=32cm

altitude ,h = 8cm (given)

Area of a trapezium = $\frac{1}{2}$(a+b)×h

Area =$\frac{1}{2}$×32×8

        =128cm
