Answer 1

Correct Question:

Find the area of trapizium whose parallel sides are 1 m and 1.2 m and perpendicular distance between them is 0.8 m.

Given:

✰ Parallel sides of trapizium are 1 m and 1.2 m

✰ Distance between them ( Height ) = 0.8 m

To find:

✠ Area of trapizium

Solution:

Parallel sides are 1 m and 1.2 m and distance between them i.e , height is 0.8 m. So, we can find area of trapizium easily by using formula.

Area of trapizium = 1/2 × ( sum of parallel sides ) × height

Area of trapizium = 1/2 × ( a + b ) × h

Here, 'a' and 'b' are the parallel sides of the trapezium and 'h' the height. Height of the trapezium is the distance between its parallel sides.

Now, put the values in formula,

Area of trapizium = 1/2 × ( a + b ) × h

➩ Area of trapizium = 1/2 × ( 1 + 1.2 ) × 0.8

➩ Area of trapizium = 1/2 × ( 2.2 ) × 0.8

➩ Area of trapizium = 1/2 × 2.2 × 0.8

➩ Area of trapizium = 1.1 × 0.8

➩ Area of trapizium = 0.88 m²

∴ Area of trapezium = 0.88 m²

Answer 2

Answer:

Given :-

• The sum of parallel sides are 1 m and 1.2 m and perpendicular distance between them is 0.8 m.

To Find :-

• What is the area of trapezium.

Formula Used :-

★ Area of trapezium = 1/2 × Sum of parallel sides × Perpendicular distance★

Solution :-

Given :

• Sum of parallel sides = 1 m and 1.2 m
• Perpendicular distance = 0.8 m

According to the question by using the formula we get,

⇒ Area of trapezium = 1/2 × 1 + 1.2 × 0.8

⇒ Area of trapezium = 1/2 × 2.2 × 0.8

⇒ Area of trapezium = 1/2 × 1.76

➠ Area of trapezium = 0.88 m²

∴ The area of trapezium is 0.88 m² .Hence, the correct options is option no 1) 0.88 m².

Let's Verify :-

↦ Area of trapezium = 1/2 × 1 + 1.2 × 0.8

Put area of trapezium = 0.88 we get,

↦ 0.88 = 1/2 × 2.2 × 0.8

↦ 0.88 = 1/2 × 1.76

↦ 0.88 = 0.88

➦ LHS = RHS

Hence, Verified ✔
