Question

Amitabh owns a rectangular plot of land.Its breadth is 7m less than its length.Perimeter of the plot is 1034m .Set up and equation for the given problem.​

Answer 1

Answer:

Answer in explanation

Step-by-step explanation:

Here, Length of Rectangular Park =l

Breadth of Rectangular Park =l−3

Altitude of Triangular Park =12

Breadth of Triangular Park =l−3

Now,

A

Rectangle

=l(l−3)

A

Triangle

=

×12(l−3)

⇒l(l−3)−

×12(l−3)=4

⇒l

−9l+14=0

⇒(l−2)(l−7)=0⇒l=2,7

Since, breadth is l−3 , l

=2

∴l=7 m and breadth =7−3=4 m

Answer 2

Answer:

Let the Length of the Park be X m

Then Breadth of the park = ( X - 7 ) M

Perimeter of Rectangle = 2 × ( L + B )

Perimeter Given = 1034 m

So we have ,

2 × ( X + X - 7 ) = 1034

2 × ( 2X - 7 ) = 1034

(2X - 7 ) = 5 17

2X = 517 + 7

2X = 524

X = 262

〰Length of plot is 262 m

〰Breadth of plot is 255 m
