Question

The length and breadth of a rectangular field are 50 m and 40 m respectively. Find perimeter​

Answer 1

180 will be the perimeter as it formula is 2(l+b) ok

Answer 2

Given:-

• The length and breadth of a rectangular field are 50 m and 40 m respectively.

Have to Find :

• Perimeter of the rectangle.

Solution:

As we know the formula for finding perimeter of rectangle.

Applying it here.

Perimeter → 2 ( l + b)

where,

" l " → length = 50 m

" b " → breadth = 40 m$.$

So, substituting the values, we get :

➹ 2( 50 + 40 )

➹ 2 × 90

➹ 180 m

Hence, The perimeter of rectangle is 180 m

➤ Some basic formulas which are really helpful in such type of questions

↬ Perimeter of Rectangle = 2( L + B )

↬ Perimeter of square = 4 × Side

↬ Perimeter of triangle = AB + BC + CA

↬ Area of Rectangle = L × B

↬ Area of Square = ( side ) ²

↬ Area of Rhombus = Product of Diagonal/2.

↬ Area of Parallelogram = Base × Height.

↬ Area of triangle = 1/2 × base × height .
