Question

a ) Length of a rectangle = 12 cm,
Breadth =10 cm
Area =
​

Answer 1

Answer:

area=length×breadth

=12×10

=120 answer

Answer 2

✧ Given :

• Length of rectangle is 12 cm.
• Breadth of rectangle is 10 cm.

✧ To Find :

• Area of rectangle ?

✧ Solution :

• We know that,

$\large\star{ \underline{\boxed{\sf{\purple{ Area _{(rectangle)} = (Length \: \times Breadth)}}}}}⋆⋆$

• Now, Substitute the values :

$➟ \: {\sf{ Area _{(rectangle)} = (12 \times 10)}}$

$➟ \: {\sf{ Area _{(rectangle)} = 120 \: cm ^{2} }}$

◙ Hence, the Area of rectangle is 120 cm².

• Some formulas to be remembered.

• Area of rectangle = Length × breadth

• Perimeter of rectangle = 2( Length + breadth )

• Area of square = (Side)²

• Perimeter of square = 4 × Side

• Perimeter of triangle = a + b + c = 2s

• Area of triangle = 1/2 × Base × height. OR, √s (s-a) (s-b) (s-c)

• Area of parallelogram = Base × Height
