Question

the shape of the top surface of a table is a trapezium . find its area if its parallel sides are 1 metre and 1.2 metre and perpendicular distance between them is 0.8 minutes .

Answer 1

Hey dear first of all correct your question it's not 0.8 minutes rather it's 0.8metre
 Area of Trapezium is given by
= (1/2) × (Sum of parallel sides) × Perpendicular distance
Here in this question, Perpendicular distance=.8  m
Parallel sides are 1m and 1.2 m
So Area of Trapezium
= (1/2) × (1+1.2) ×.8
=.88 m^2
Hope it helped you

Answer 2

$\pink{area \: of \: trapezium = \frac{1}{2} \times sum \: of \: parallel \: sides \times perpendicular \: distance }$

$\pink{parallel \: sides = 1 \: and \: 1.2m}$

$\pink{so... area = \frac{1}{2} \times (1 + 1.2) \times 0.8}$

$\huge\pink{ = 1.1 \times 0.8}$

$\huge\pink{ {=0.88m}^{2} }$
