Question

3/ Find the length of rectangles whose areas and breadths are as follows .

b. Area = 94.3 sq. cm; Breadth = 8.2 cm
​

Answer 1

SOLUTION

Given Rectangle -

Breadth = 8.2 cm

Area=94.3 cm^2

Formula suitable →

Length = Area/ Breadth

94.3/8.2

= 11.5 cm

ANSWER

LENGTH OF RECTANGLE IS 11.5 CM

Answer 2

Before, finding the answer. Lets find out on how we can find the answer.

• To find the Length, we must use the formula of :

$\sf \dfrac{area}{breadth}$

____________________

Given :

• Area = 94.3 sq.cm
• Breadth = 8.2 cm

To find :

• Length

Formula :

$\sf \dfrac{area}{breadth}$

Solution :

We know that,

$\sf length = \dfrac{area}{breadth}$

$\sf = \dfrac{94.3}{8.2}$

$\sf = 11.5 \: cm$

Hence, Length is 11.5 cm.

★ Verification :

Area of Rectangle = l × b

Where,

l = length

b = breadth

----------

94.3 = 11.5 × 8.2

= 94.3

Hence, L.H.S = R.H.S
