$\large \bold \color{green}{Solve: }$
a) If the base of a parallelogram is 8 cm and height is 5 cm then find its srea.
b) If area of a parallelogram is 112 sq cm and base of it is 10 cm then find its height.
c) If base of a parallelogram is 18 cm and its height is 11 cm, find its area.​

Answer 1

a) If the base of a parallelogram is 8cm and height is 5cm then find its area.

We know that, the area of a parallelogram is equal to the product of base and height of a parallelogram. Mathematically;

→ Area of parallelogram = b * h

where, b is the base of a parallelogram and h is the height of a parallelogram.

By substituting the given values in the formula, we get the following results:

→ Area of parallelogram = 8 * 5

→ Area of parallelogram = 40

Hence, the area of a parallelogram with base 8cm and height 5cm is 40cm².

b) If area of a parallelogram is 112 sq cm and base of it is 10 cm then find its height.

We can find the height of the given parallelogram by using the formula for area of a parallelogram.

We know that, the area of a parallelogram is equal to the product of base and height of a parallelogram. Mathematically;

→ Area of parallelogram = b * h

where, b is the base of a parallelogram and h is the height of a parallelogram.

By substituting the given values in the formula, we get the following results:

→ 112 = 10 * h

→ h = 112/10

→ h = 11.2

Hence, the height of the given parallelogram is 11.2cm.

c) If base of a parallelogram is 18cm and its height is 11cm, find its area.

We know that, the area of a parallelogram is equal to the product of base and height of a parallelogram. Mathematically;

→ Area of parallelogram = b * h

where, b is the base of a parallelogram and h is the height of a parallelogram.

By substituting the given values in the formula, we get the following results:

→ Area of parallelogram = 18 * 11

→ Area of parallelogram = 198

Hence, the area of a parallelogram with base 18cm and height 11cm is 198cm².

Answer 2

QUESTION :-

• a) If the base of a parallelogram is 8 cm and height is 5 cm then find its area

• b) If area of a parallelogram is 112 sq cm and base of it is 10 cm then find its height.

• c) If base of a parallelogram is 18 cm and its height is 11 cm, find its area

GIVEN :-

• a) base of a parallelogram is 8 cm and height is 5 cm

• b) area of a parallelogram is 112 sq cm and base of it is 10 cm

• c) base of a parallelogram is 18 cm and its height is 11 cm

TO FIND :-

• a) find its area = ?

• b) find its height = ?

• c) find its area = ?

SOLUTION :-

a) answer =

Area of a parallelogram = base × height

= 8 × 5

= 40

area of the parallelogram is 40 sq.cm

b) answer =

Area of a parallelogram = base × height

112 = 10 × height

112/10 = height

height of the parallelogram is 11.2 cm

C) answer =

For a parallelogram,

Base = 18 cm , Height = 11 cm

Area of Parallelogram = Base × Height

= 18 × 11

= 198 cm²

Area of parallelogram = 198 cm²
