Question

Choose the The area of a trapezium with parallel sides 18 cm, 12 cm and height 5 cm is

(a) 60 cm

(b) 90 cm

(c) 75 cm?

(d) 150 cm

5 cm​

Answer 1

Answer:

c)75cm

here height=5pm

parallel sides 18 cm, 12 cm

area of trapezium=18+12/2×5

=75cm

Answer 2

Correct Question :-

Choose the The area of a trapezium with parallel sides 18 cm, 12 cm and height 5 cm is _____

• (a) 60 cm²
• (b) 90 cm²
• (c) 75 cm²
• (d) 150 cm²

Answer :-

[ Option. c ] 75cm² is the correct option.

• The area of trapezium is 75cm²

Step-by-step explanation ::

To Find :-

• The area of trapezium

Solution :-

Given that,

• The two parallel sides of trapezium are 18cm and 12cm
• Height of trapezium is 5cm

As we know that,

Area of trapezium = 1/2 × ( a + b ) × h,

Where,

• a and b are the two parallel sides of trapezium
• h is the height [ distance between the two parallel sides ]

=> Area of trapezium = 1/2 × ( 18 + 12 ) × 5

=> Area = 1/2 × 30 × 5 .... dividing 30 and 2 with 2,

=> Area = 1 × 15 × 5

=> Area = 75

The area of trapezium is 75cm².
