Question

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

Answer 1

Step-by-step explanation:

now given the top surface area is in the shape of trapezium

Area of the top surface ( trapezium)

= 1/2× sum of parallel sides × perpendicular distance ( height )

so, Area = 1/2 × ( 1+ 1.2 ) × 0.8

= 1.1 × 0.8

= 0.88 m. sq.

Answer 2

☆ Solution ☆

Given :-

• a = 1.2 m
• b = 1 m
• h = 0.8

To Find :-

• Area of table

Step-by-Step-Explaination :-

$\tt{Parallel\: sides} = 1m\: and\: 1.2m$

$\longrightarrow\tt{Height(h)=0.8m}$

$\tt{As\: we\: know\: that} :-$

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

$\tt{ Putting \: respective \: value}$

$\longrightarrow\dfrac{1}{2}\times 1 + 1.2 \times 0.8$

$\longrightarrow\dfrac{1}{2}\times\dfrac{22}{10}\times\dfrac{0.8}{10}$

$\longrightarrow\dfrac{179}{200}$

$\longrightarrow 0.88 {m}^{2}$

Hence,

The Area of top surface of the table is 0.88m ${m}^{2}$
