Question

If the area and the breadth of a rectangle are 31.25 cm2 and 0.025 m. Find the lengthof rectangle in cms​

Answer 1

$\large\bf\underline \orange{Given:-}$

• Area of rectangle = 31.25cm²
• Breadth = 0.025m

$\large\bf\underline \orange{To \: find:-}$

• length of rectangle.

$\huge\bf\underline \green{Solution:-}$

• Breadth = 0.025 = 2.5cm

• Let the length be x m

We know that,

area of rectangle = length×breadth.

⠀⠀⠀⠀⠀➝ 31.25 = 2.5 × x

⠀⠀⠀⠀⠀➝ 31.25/2.5 = x

⠀⠀⠀⠀⠀➝ 12.5 = x

So,

The length of rectangle is 12.5cm.

Some Important concepts:-

perimeter of rectangle = 2(l+b)

Area of rectangle = l×b

Each Angle of rectangle is of 90°

Answer 2

Given ,

Area of rectangle = 31.25 cm²

Breadth of rectangle = 0.025 m or 2.5 cm

Let , the length of rectangle be " x "

We know that , the area of rectangle is given by

$\large \mathtt{ \fbox{Area = Length \times Breadth }}$

Thus ,

$\Rightarrow \sf 31.25 = x \times 2.5 \\ \\ \Rightarrow \sf x = \frac{31.25}{2.5} \\ \\\Rightarrow \sf x = 12.5 \: \: cm$

$\therefore \bold{\sf \underline{The \: length \: of \: rectangle \: is \: 12.5 \: cm}}$
