Question

if the poster length is 30cm and width is 28cm then find it's area and perimeter ​

Answer 1

Answer:

area=240cm perimeter = 480cm

Answer 2

Given,

length = 30cm, width = 28cm

Since, length is not equal to width we can say that the poster is in rectangle shape

We know that,

Area = l × b;where l = length, b = breadth

Perimeter = 2(l+b)

Now,

area = 30×28 = 840 cm²

Perimeter = 2(30+28) = 58 cm

Therefore,

Area = 840cm²

Perimeter = 58cm
