Question

area of rectangle is 48 square CM if the breadth is 3 cm find the length​

Answer 1

Answer:

21 is the length of one side

Step-by-step explanation:

3 is the breadth then there are two side that is 3+3 =6

then subtract 6 from 48 =42

42÷2=21

Answer 2

Step-by-step explanation:

Question :-

• Find the length of the rectangle whose area is 48 cm² and breadth is 3 cm.

To Find :-

• Length of rectangle.

Solution :-

Given :

• Area = 48 cm²
• Breadth = 3 cm

By using the formula,

${\sf{\longrightarrow Area\ of\ rectangle\ =\ l \times b}}$

Where,

• l = length
• b = breadth

According to the question, by using the formula, we get :

${\sf{\longrightarrow Area\ of\ rectangle\ =\ l \times b}}$

${\sf{\longrightarrow 48\ =\ l \times 3}}$

${\sf{\longrightarrow \dfrac{48}{3}\ =\ l}}$

${\sf{\longrightarrow 16\ =\ l}}$

${\sf{\longrightarrow l\ =\ 16\ cm}}$

$\therefore$ Hence, length of rectangle is 16 cm.
