Question

find the area of Trapezium height is 7 cm and one parallel side is 8 cm and 12 cm. Find the area.
​

Answer 1

Answer:70cm^2

Step-by-step explanation:

Area of a trapezium is half of the sum of the parallel sides times the height i.e., (a+b)h1/2

Here a=8cm ,b=12cm

h=7cm

So area = 1/2(8+12)7=70cm^2

Answer 2

GIVEN:

• Height of trapezium = 7 cm
• parallel sides of trapezium = 8 cm and 12 cm.

TO FIND:

• What is the area of the trapezium ?

SOLUTION:

We have given that, the height of trapezium is 7 cm and parallel sides are 8 cm and 12 cm.

We know that, the formula for finding the area of trapezium is :-

$\bf{\star \: Area \: of \: Trapezium = \frac{1}{2} \times (sum \: of \: parallel \: sides) \: \times height \: \star}$

According to question:-

$\sf{\mapsto Area = \frac{1}{2} \times (8 + 12) \: \times 7}$

$\sf{\mapsto Area = \frac{1}{\cancel{2}} \times \cancel{20}\: \times 7}$

$\sf{\mapsto Area = 10 \: \times 7}$

$\bf{\mapsto \: \star \: Area = 70 \: cm^2\: \star }$

❝ Hence, the area of trapezium is 70 cm² ❞

✰ Extra Information ✰

➠ One pair of opposite sides is parallel.

➠ Non- parallel sides are equal in trapezium.
