Question

what is the length of a rectangle with area 4.5 sq m and breadth 1.5 m?

Answer 1

area = length × breadth

let length be x

4.5 = x × 1.5

x = 4.5 ÷ 1.5

x = 3..

hope this helps u...

Answer 2

$\textbf{\underline{Answer :-}}$

The Breadth of the Rectangle is 3m

$\textbf{\underline{Explanation :-}}$

$\textsf{\underline{Given :-}}$

Breadth of the Rectangle = 1.5 m

Area of the Rectangle = 4.5 sq m

$\textsf{\underline{To find :-}}$

The Length of the Rectangle

$\textsf{\underline{Solution :-}}$

Area of Rectangle =

$\tt{\implies \: length \times breadth}$

Consider Length as x

$\tt{\implies \: x \times 1.5 \ = 4.5}$

$\tt{\implies \: x = \dfrac{4.5}{1.5} }$

Convert decimal into a number

$\tt{\implies \: x = \dfrac{4.5 \times 10}{1.5 \times 10} }$

$\tt{\implies \: x = \dfrac{45}{15} }$

$\tt{\implies \: x \: = 3}$

$\therefore$The Length of the Rectangle is 3 m

Verification :-

$\tt{\implies \: 3 \times 1.5 = 4.5}$

$\tt{\implies4.5 = 4.5}$

$\therefore$The Breadth of the Rectangle is 3m
