Answer:

600 cm²

Step-by-step explanation:

<u>We know that:</u>

  • Length:Breadth = 3:2

<u>Solution:</u>

  • Length:Breadth = 3:2
  • => Length:Breadth = 3x:2x
  • => 3x + 2x + 3x + 2x=100 cm
  • => 10x=100 cm
  • => x = 10 cm
  • => Length = 30 cm
  • => Breadth = 20cm
  • => Area_{rectangle}  = 30(20) cm^{2}
  • => Area_{rectangle}  = 600 cm^{2}

Hoped this helped!

First of all We will find the length and breadth with the help of perimeter and then find the area...

Ratio of length to breadth is 3:2, So let length be 3x and breadth be 2x

ATQ,

\boxed{ \mathfrak{perimeter = 2(l + b)}}

\tt \: 100 = 2 \times (3x + 2x)

\tt \: 50 = 3x + 2x

\tt \: 50 = 5x

\tt \: 10 = x \: or \: x = 10

<h3>Now, </h3>

\sf \: length = 3x  \\  \sf= 3 \times 10 \\  \sf \:  = 30 \: cm

\sf \: breadth = 2x  \\  \sf= 2 \times 10 \\  \sf \:  = 20 \: cm

<h3>Finding area⤵️</h3>

\boxed{ \mathfrak{area = l \times b}}

\tt \: area = 30 \times 20 \\  \tt \:  = 600 {cm}^{2}

at first the average mass some durians was 3.4kg.when 2 durians were added the aevrage mass of the 2 durians was 1.3kg was added
LekaFEV [45]

We conclude that the initial number of durians is 12.

<h3>How many durians were there at first?​</h3>

Let's say that initially, we had N durians, such that these N durians have an average mass of 3.4kg.

When 2 durians  (with an average mass of 1.3kg) more are added, the new average mass is given by:

(N*3.4kg + 2*1.3kg)/(N + 2)

And we know that the above amount is equal to 3.1kg, then we can write:

(N*3.4kg + 2*1.3kg)/(N + 2) = 3.1kg

Now we can solve this equation for N:

(N*3.4kg + 2.6kg) = 3.1kg*(N + 2)

N*(3.4kg - 3.1kg) = 6.2kg - 2.6kg

N*(0.3kg) = 3.6kg

N = (3.6kg)/(0.3kg) = 12

We conclude that the initial number of durians is 12.
