Answer 1

$\rm\underline\bold{Question \purple{\huge{\checkmark}}}$

Find the area of a rectangle whose

(i) length = 5m 60 cm and breadth = 3 m 40 cm

$\huge{\tt{\colorbox{lime}{AnswEr:}}}$

length=5m60cm=5.60m

breadth =3m40cm=3.40m

Now,

area=length*breadth

=5.60*3.40

=19.0400

=19m04cm

✰ Here, the question has given us the Length and the Breadth of the rectangle in m and cm. To find the area of the rectangle we need to first convert the length and breadth into metre or cm. And after that by applying the formula of the area of the rectangle we will find out the area of it.

ANSWER:-

• Area of the rectangle in metres is 19.04m².
• Area of the rectangle in cm is 190400cm².

GIVEN:-

• Length of the rectangle = 5m 60cm
• Breadth of the rectangle = 3m 40cm

TO FIND:-

• Area of the rectangle = ?

FORMULA:-

• Area of the rectangle = Length × Width

SOLVING BY APPLYING THE FORMULA:-

✪ 1st way = We can convert the length and the breadth in metre.

✫ Converting the length into m ⇩

» 5m 60cm

» 5m + (60/100)m... [As 1cm = 1/100 cm]

» 5m + 0.6m

» 5.6m

✫ Converting the breadth into m ⇩

» 3m 40 cm

» 3m + (40/100)m... [As 1cm = 1/100cm]

» 3m + 0.4m

» 3.4m

So, now length is 5.6 m and breadth is 3.4m.

✦Area of rectangle = Length × Breadth

» Area = 5.6m × 3.4m

» Area = 5.6m × 3.4m = 19.04m²

» Area = 19.04m²

✪ 2nd way = We can convert the length and the breadth in cm.

✫ Converting the length into cm ⇩

» 5m 60cm

» 5 × 100cm + 60cm... [As 1m = 100cm]

» 500cm + 60 cm

» 560 cm

✫ Converting the breadth into cm ⇩

» 3m 40cm

» 3 × 100cm + 40cm... [As 1m = 100cm]

» 300cm + 40cm

» 340cm

✦Area of rectangle = Length × Breadth

» Area = 560cm × 340cm

» Area = 560cm × 340cm = 190400cm²

» Area = 190400cm²
