Answer 1

Given -

• Length of rectangle = 9.25m

• Breadth of rectangle = 8.50m

To find -

• Perimeter of the rectangle

Solution -

Perimeter of rectangle = 2(l + b)

Where,

L = Length

B = Breadth

On substituting the values -

Perimeter of rectangle = 2(9.25 + 8.50)m

Perimeter of rectangle = 2(17.75)m

Perimeter of the rectangle = 35.5m²

$\therefore$ The perimeter of the rectangle is 35.5m²

Other formule -

• Area of rectangle = L × B

• Area of square = side × side

• Perimeter of square = 4 × side

• Area of triangle = 1/2 × base × altitude\height

• Perimeter of triangle = a + b + c

Answer 2

$\huge{\boxed{\rm{Question}}}$

Length and breadth of a rectangle are 9.25 m & 8.50 m. What is the perimeter of the rectangle.

$\huge{\boxed{\rm{Answer}}}$

$\large{\boxed{\boxed{\sf{Given \: that}}}}$

• Length of rectangle = 9.25 metres.

• Breadth of rectangle = 8.50 metres.

$\large{\boxed{\boxed{\sf{To \: find}}}}$

• Perimeter of rectangle.

$\large{\boxed{\boxed{\sf{Solution}}}}$

• Perimeter of rectangle = 35.5 metres

$\large{\boxed{\boxed{\sf{We \: also \: write \: these \: as}}}}$

• Length as L.

• Breadth as B.

• Perimeter as P.

$\large{\boxed{\boxed{\sf{Using \: formulas}}}}$

• Perimeter of rectangle = 2(l+b)

$\large{\boxed{\boxed{\sf{What \: does \: the \: question \: says}}}}$

$\large{\boxed{\boxed{\sf{Let's \: understand \: the \: concept \: 1st}}}}$

• This question says that there is a rectangle. It's length and breadth are given respectively 9.25 m and 8.50 m. Now, it says that we have to find the perimeter of rectangle.

$\large{\boxed{\boxed{\sf{How \: to \: do \: this \: question}}}}$

$\large{\boxed{\boxed{\sf{Let's \: see \: the \: procedure \: now}}}}$

• To solve this question we have to use the formula to find perimeter of rectangle that is 2(l+b). Afterthat according to this formula we have to put the values. We have to put 9.25 as l and 8.50 as b. After putting them we get 2(9.25 + 8.50). Now add the digits we get 17.75 afterthat multiplying this by 2 we get 35.5 m as our final result . Thus, we get 35.5 metres as the perimeter of rectangle.

$\large{\boxed{\boxed{\sf{Full \: solution}}}}$

According to this question, we already know that what is given or what to find. We have given with l and b and we have to find the perimeter.

So, let's see formula to find perimeter of rectangle again.

• Perimeter = 2(l+b)

Where,

• l is length.

• b is breadth.

• p is perimeter.

Putting the values we get the following results.

➝ P = 2(l+b)

➝ P = 2(9.25 + 8.50)

➝ P = 2(17.75)

➝ P = 35.5 metres.

Henceforth, perimeter of rectangle is 35.5 metres.
