Question

7. A rectangle has same area as that of a square of side 10 m. If the breadth of the
rectangle is 8 m, find the perimeter of the rectangle.​

Answer 1

Answer:

41 metre

Step-by-step explanation:

Area of square = ( Side )²

Area of given square = ( 10m )² = 100m²

Area of Rectangle = Length * Breadth

It is given that area of rectangle = area of rectangle

Length * 8m = 100m² ( Breadth = 8m )

Length = 100/8 m

Length = 12.5 m

Now,

Perimeter of rectangle = 2( Length + Breadth )

Perimeter of rectangle = 2( 12.5 + 8 )

Perimeter of rectangle = 41m

Thank you.

Answer 2

Answer:

<< 41 m >>

Step-by-step explanation:

[Please Follow the respective Steps]

Given,

≈≈> Area of square = Area of Rectangle

≈≈> Side length of Square = 10 m

≈≈> 10 × 10 = L × b

≈≈> 100 = L × 8 (b = 8)

≈≈> 100 ÷ 8 = L

≈≈> L = 12.5

Required ----- Perimeter of The Rectangle

≈≈> 2 ( L + b)

≈≈> 2 ( 12.5 + 8 )

≈≈> 2 ( 20.5 )

≈≈> 41 m
