Question

2. The shape of a top surface of table is a trapezium. Find the area if its parallel sides
are 1.5 m and 2.5 m and perpendicular distance between them is 0.8 m.​

Answer 1

Answer:

area of trapezium = 1/2(sum of parallel sides) perpendicular distance

= 1/2(1.5+2.5)*0.8

=1.6m2

Answer 2

$\sf \red{Given \: that ;} \\ \sf \pink{Parallel \: sides \: are \: 1.5 m \: and 2 m.} \\ \sf \pink{Distance \: between \: them \: is \: 1.2 m.}$

$\sf{Here,} \\ \sf{⇛a = 1.5 m,} \\ \sf{⇛= 2 m,} \\ \sf{⇛h = 1.2 m.}$

$\sf{Area \: of \: Trapezium = \frac{1}{ 2} \times ( a + b ) \times h} \\ \sf{= \sf{ \frac{1}{ 2} \times ( 1.5 + 2 ) \times 1.2}} \\ = \sf{frac{4.2}{2}} \\ = \sf{2.1 m²}$

$\sf \red{Hence, \: the \: area \: of \: trapezium \: is \: 2.1 m²}$
