Question

Find the perimeter and area of a rectangle length 15 cm breath 20 cm

Answer 1

Answer:

perimeter=70cm

area=300cm²

Step-by-step explanation:

Given- length of rectangle=15 cm

           Breadth "    "           =20 cm

To find- perimeter "  "   and are of rectangle.

Solution,

perimeter of rectangle = 2(l+b)

                                      = 2(15+20)

                                      = 2(35)

                                      = 70 cm is the answer.

area of rectangle = l×b

                             = 15×20

                             = 300 cm² is the answer.

HOPE THIS IS HELPS YOU MATE!!

Answer 2

Answer :-

Area = 300cm²

Perimeter = 70cm

_____________________

Solution :-

Given :-

Length = 15 cm

Breadth = 20 cm

To Find :-

Area and Perimeter of Rectangle.

Step By Step Explanation :-

Area of Rectangle = Length × Breadth

Area = 15 × 20 cm²

Area = 300 cm²

Perimeter of Rectangle = 2 ( Length + Breadth )

Perimeter = 2 ( 15 + 20 ) cm

Perimeter = 2 × 35 cm

Perimeter = 70 cm

_____________________

Formula Used :-

• Perimeter = 2 ( Length + Breadth )

• Area = Length × Breadth
