Question

The length of a rectangle is 1.5m, If it's area is 14.295 sqm. Find the breadth.

• A. 9 m
• B. 9.2 m
• C. 9.53 m
• D. None of these

Answer 1

The correct option is C 9.53 m

$\text{Area of rectangle}=\text{length}\times \text{breadth}$

$14.295=1.5\times breadth$

$breadth=14.295÷1.5$

Get rid off decimal from the divisor as follows,
$breadth=\frac{14.295\times 10}{1.5\times 10}$

$breadth=\frac{142.95}{15}=142.95÷15$
Step 1: Count the number of digits after the decimal in dividend.

Step 2: Ignore a decimal point and perform the long division, as you would with whole numbers as follows

Step 3: Now place a decimal point back.
142.95 has 2 decimal places. So, place the decimal point 2 places to the left in the quotient 953.

Breadth of the rectangle is 9.53 m
