Question

class 5
find the perimeter of rectangles
a). length= 20cm; breadth=15cm
​

Answer 1

Answer:

70cm

Step-by-step explanation:

Perimeter=2(l+b)

2(20+15)

2(35)

70

Answer 2

Here the dimensions of a rectangleis given:

Length = 20 cm  

Breadth = 15 cm

We have to find the perimeter of the rectangle

We will use the formula of the perimeter of a rectangle

Perimeter of rectangle = 2( length + breadth)

Perimeter of the rectangle = 2 (20 + 15)

                                            = 2 (35)

                                            = 70 cm

Hence, the perimeter of the rectangle will be 70 cm
