Question

$area of rectangle = 7200sq$
area of rectangle is equals to 7200 square metre length is equals to 80 what is the breadth ​

Answer 1

Answer :

$\boxed{\boxed{\mathsf{Breadth = 90m}}}$

Step-by-Step Explanation :

Given

• Area of rectangle is equals to 7200m^2
• Length = 80m

To Find

• Measure of Breadth

Solution

Now According to question

$\mathsf{\longrightarrow \: Length \: of \: Rectangle = 80m}$

$\mathsf{\longrightarrow \: Now \: Let \: Breadth \: of \: Rectangle \: be = X}$

Now we know that

$\boxed{\boxed{ \bigstar \: \mathsf{Area \: of \: Rectangle \: = (Length) \times (Breadth)}}}$

So here

$\mathsf{\longrightarrow \: Area \: of \: Rectangle \: = 7200m^2}$

$\mathsf{\longrightarrow \: 7200m^2 =( Length) \times (Breadth)}$

$\mathsf{\longrightarrow \: 7200m^2 =( 80m) \times (x)}$

• taking 80 to LHS we have ,

$\mathsf{\longrightarrow \dfrac{7200m^2}{80m} = x\:}$

$\mathsf{\longrightarrow x = 90m}$

Therefore we have

$\mathsf{\longrightarrow \: Breadth \: of \: Rectangle \: = X = 90m}$

• Verification

Now we know

$\leadsto \mathsf{Area \: of \: Rectangle \: = (Length) \times (Breadth)}$

$\leadsto \mathsf{Area \: of \: Rectangle \: = (80m) \times (Breadth)}$

• putting value of breadth obtained ^

$\leadsto \mathsf{7200m^2\: = (80m) \times (90m)}$

$\leadsto \mathsf{7200m^2\: = 7200m^2}$

Hence verified

$\underline{\mathsf{Formulas \: Related \: to \: Rectangle}}$

$\to \mathsf{Area \: = (Length) \times (Breadth)}$

$\to \mathsf{Perimeter \: = 2(Lenght + Breadth)}$

$\underline{\mathsf{Formulas \: Related \: to \: Square }}$

$\to \mathsf{Area \: = (Side)^2}$

$\to \mathsf{Perimeter \: = 4(Side)}$

$\underline{\mathsf{Formulas \: Related \: to \: Triangle }}$

$\to \mathsf{Area \: = \dfrac{1}{2} \times (Base) \times (Height)}$

$\to \mathsf{Perimeter \: = Sum \: of \: all\: side}$

To answer questions similar to above question.

• We just need to insert the unknown measures in the formulas related to it as per the question.

to form a question with only one variable.

•Then just solve the equation formed.

• Thus by this you would be able to get the value of unknown.

Answer 2

$\Large\underline{\underline{\sf{Given}:}}$

• Area of Rectangle = 7200m²
• Length of Rectangle = 80m

${\large\bf{\mid{\overline{\underline{To\:Find}}}\mid}}$

• Breadth of rectangle ???

$\Large\underline{\underline{\sf{Solution}:}}$

$\textbf{we know that, Area of Rectangle}$ =

$\large\boxed{\bold{ Area = Length × Breadth}}$

$\textbf{Or, we can say that,,}$

$\large\boxed{\bold{Breadth = \frac{Area}{Length}}}$

$\textbf{Putting Values Now, we get:-}$

$\red\leadsto \: \green{Breadth} = \pink{\frac{ \cancel{7200}}{ \cancel{80}}} = \large\boxed{\bold{90cm}}$

Hence, Breadth of Rectangle will be 90cm.
