Question

What is the length of A rectangle with area 4.5square meter and the breadth 1.8 meter

Answer 1

Answer :

• Length of rectangle is 2.5m

Given :

• Area of rectangle = 4.5m²
• Breadth of rectangle = 1.8m

To find :

• Length of rectangle

Solution :

• Let the length of rectangle be l
• Breadth of rectangle = 1.8m

We know that

• Area of rectangle = l × b

Where,

• l is length of rectangle
• b is breadth of rectangle

Given , Area is 4.5m²

》Area of rectangle = l × b

》4.5 = l × 1.8

》l = 4.5/1.8

》l = 2.5m

Hence, Length of rectangle is 2.5m

Verification :

• Area of rectangle = l × b

Where,

• Length of rectangle = 2.5m
• Breadth of rectangle = 1.8m

》Area of rectangle = l × b

》4.5 = 2.5 × 1.8

》4.5 = 4.5

Hence , Verified

We know that,

$\underline{ \boxed{ \sf{Area_{(rectangle) }\: = length \times breadth}}}$

$\begin{gathered} \: \: \: \: \sf \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \dashrightarrow \: 4.5 = length \times 1.8 \\ \\ \: \: \: \: \sf \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \dashrightarrow \: length = \cancel{ \frac{4.5}{1.8}} \\ \\ \sf \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \dashrightarrow \: \underline{ \boxed{ \sf{length = 2.5}}} \end{gathered}$
