Question

4. The perimeter of a trapezium is 84 cm
and its non parallel sides are 12 cm each. If
its height is 10 cm, then the area of
trapezium is
O a. 120 cm
O b. 110 cm
O c. 300 cm
O d. 200 cm​

Answer 1

Answer:

Area of the trapezium is c. 300cm ☑

Step-by-step explanation:

We know that,

Perimeter of a trapezium : a + b + c + d (sum of all sides)

So,

=> 84 = a + b + 12 + 12

=> 84 = a + b + 24

=> 84 - 24 = a + b

=> a + b = 60cm

Now,

Area of trapezium : ½(a + b) × h

= ½ × 60 × 10

= 300cm.
