Question

27: Length of Rectangle is 25m and its breadth is 20m. Find its perimeter.​

Answer 1

Answer:

90

Step-by-step explanation:

Perimeter of the rectangle = 2(l + b) 

L=25m

B=20m

perimeter, p=2*(20+25)

p=2*(45)

p=90

Answer 2

Perimeter of a Rectangle = 90 cm

Step-by-step explanation:

GIVEN

Length = 25 cm

Breadth = 20 cm

___________________________

To find

Perimeter of the rectangle

___________________________

Formulas of rectangle

Area of a Rectangle (A) = l × b

Perimeter of a Rectangle (P) = 2 ( l + b )

Diagonal of a Rectangle (D) = √l²+b²

___________________________

We know that,

Perimeter of a Rectangle = 2 ( l + b )

Perimeter of a Rectangle = 2 × ( 25 + 20 )

Perimeter of a Rectangle = 2 × 45

Perimeter of a Rectangle = 90 cm
