Question

The length of a rectangle is 5 cm more than the breadth, If the perimeter rectangle is 50 cm, find its area.​

Answer 1

Answer:

Area of rectangle is 300 sq. cm

Step-by-step explanation:

Let the breadth of the rectangle be x cm

therefore, length=(x+5) cm

breadth=x cm

According to question,

2{(x+5)+5} =50

or, 2(x+10) =50

or, 2x+20=50

or, 2x=50-20=30

or, x=30/2=15

breadth=x=15 cm

length=x+5=15+5=20 cm

We know that area of rectangle=length x breadth

=20 x 15

=300 sq. cm

Answer 2

✨ let the breadth of the rectangle be x cm .

According to the question

length = x + 5 cm

perimeter = 2 ( length + breadth )

70 = 2 ( x + 5 + x )

70 / 2 = 2x + 5

35 = 2x + 5

35 - 5 = 2x

30 = 2x

30 /2 = x

x = 15 cm

Now ,

➡️ breadth = 15 cm

➡️ length = x + 15 = 15 + 5 = 20 cm

here in this question we have to find the area of the rectangle .

So ,

✨. Area of rectangle = length × breadth

Area = 20 × 15 = 300 cm²
