Answer 2

Answer:

Given :-

First parallel side of trapezium = 20 cm

Second parallel side of the trapezium = 32 cm

Non parallel sides of the trapezium = 10 cm

To Find :-

Area of the trapezium.

Solution :-

We know that,

✮ \pink\sf{Area\:of\:trapezium = \dfrac{1}{2} \times height \times (a+b)}Areaoftrapezium=

2

1

×height×(a+b)

Here,

❒ h = 10 cm

❒ a = 20 cm

❒ b = 32 cm

So,

\blue\dashrightarrow \:\: \sf{Area = \dfrac{1}{2} \times 10 \times (20+32)}⇢Area=

2

1

×10×(20+32)

\blue\dashrightarrow \:\: \sf{Area = 5 \times (20+32)}⇢Area=5×(20+32)

\blue\dashrightarrow \:\: \sf{Area = 5 \times 52}⇢Area=5×52

\blue\dashrightarrow \:\: \sf{Area = 260\:cm^2}⇢Area=260cm

2

∴ Area of the trapezium = 260 cm²
