are 45cm and 8 cm, find its area.​

Answer 1

Answer:

area=180cm^2

Step-by-step explanation:

A=pq

2=45·8

2=180cm²

Answer 2

$\sf{\huge{\mathbb{\pink{\bigstar{\boxed{\boxed{Question}}}}}}}$

• Lengths of the diagonals of a Rhombus are 45cm and 8 cm, find its area.

$\sf{\huge{\mathbb{\pink{\bigstar{\boxed{\boxed{Solution}}}}}}}$

$\sf{\bold{\green{\underline{\underline{Given}}}}}$

• Length of 1st diagonal = 45cm
• Length of 2nd diagonal = 8cm

$\sf{\bold{\blue{\underline{\underline{To\:Find}}}}}$

• Area of the rhombus = ????

$\sf{\bold{\purple{\underline{\underline{Explanation}}}}}$

$\sf{\bold{\red{\boxed{area = \dfrac{1}{2}\times diagonal_1 \times diagonal_2}}}}$

$\sf\implies{area = \dfrac{1}{\cancel{2}}\times \cancel{8} \times 45}$

$\sf\implies{area = 4 \times 45}$

$\sf\implies{area = 180cm^2}$

$\sf{\bold{\red{\boxed{\dag area = 180cm^2}}}}$

• All sides of the rhombus are equal .
• Diagonals of the rhombus bisect at 90'
• Diagonals of the rhombus bisect each other .
• If all angles of a rhombus are 90' then it will be known as square .
