Question

length of the field is 5 m more than its breadth if perimeter is 30m the area is​

Answer 1

$\huge\color{pink}{\bf{Answer}}$

Let the Breadth be x

Length=x+5

Given perimeter=30cm

Perimeter=2×(l+b)

=>2×[(x+5)+x]=30

=>2x+10+2x=30

=>4x+10=30

=>4x=30-10

=>4x=20

=>x=20/4

=>x=5

Breadth=5m

Length=x+5=5+5=10m

Area=l×b

=>10×5=50m²

Answer 2

Answer:

Here , length and breadth are mentioned, the field is regtangle.

$l \: = \: 5 + b$

Perimeter of regtangle = 2 (l + b)

thus,

$30 = 2(l + b) \\ 15 = l + b$

We know that, L = 5 + b

$15 = 5 + b + b \\ 10 = 2b \\ b = 5$

Now , b = 5

$l = 5 + b \\ = 5 + 5 = 10$

Here , l = 10 and b = 5

Area of regtangle = l x b

= 10 x 5

= 50

Therefore, the area of triangle is 50m².
