Question

perimeter of a rectangular field is 86m if its breath is 25 m find the length and area

Answer 1

Step-by-step explanation:

Given:-

Perimeter of rectangle = 86m

Breath of rectangle ( b ) = 25m

We have to find :-

Area of rectangle and lenght of rectangle ( l )

Solution:-

Perimeters of rectangle = 2 ( l × b )

• 86 = 2 ( l × 25 )
• 86/2 = l × 25
• 43 = l × 25
• 43 / 25 = l
• l = 1.72 m

Now, Area of rectangle = l × b

• Area = 1.72 × 25
• Area = 43 m²

Answer 2

Given:

perimeter P=86m

breath B=25 m

p=2(l + b)

86=2(l+25)

86=2l+50

2l=86-50

2l=36

l=36/2

l=18 m

area of rectangle=length × breadth

=18 × 25

=450

Hence  length is 18m and area is 450 m²
