Question

If the area of parallelogram is 36 cm² and base is 9cm find corresponding height​

Answer 1

Given:-

• Area of parallelogram = 36cm²
• Base of parallelogram = 9cm

To Find:-

• Height = ?

$\small\mathfrak{\color{red}{\underline{\underline{Answer♡}}}}$

Area of parallelogram = 36cm²

→ Base × Height = 36cm²

$9 \times height = 36 \\ \\ height = \frac{36}{9}$

$height = 4cm$

• Height of parallelogram = 4cm.

Answer 2

Given :

• Area of parallelogram is 36 cm².
• Base of parallelogram is 9cm.

To Find :

• Height of parallelogram ?

Formula used :

• Area of parallelogram = B × H

Here,

• B = Base of a parallelogram
• H = Height of a parallelogram

Finding the Height of a parallelogram :

ㅤㅤㅤㅤㅤㅤ→ 36 cm² = 9 × H

ㅤㅤㅤㅤㅤㅤ→ 36/9 = H

ㅤㅤㅤㅤㅤㅤ→ 4 cm = Height

ㅤㅤㅤㅤㅤㅤ

ㅤ∴ Height of a parallelogram is 4 cm.

ㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤ

Some formulas to be remembered :-

• Area of rectangle is L × B

• Area of Square is (Side)²

• Area of triangle is 1/2 × b × h or √s(s-a) (s-b) (s-c)

• Area of Circle is πr²

• Area of Trapezium is 1/2 × h (a+b)

• Area of Rhombus is 1/2 × d₁ × d²
