Answer 1

so
A.T.Q
area =l×b
(1.5×20)cm²
30cm²
so the piece of paper of dimensions 1.5m×20cm is 30cm².
I hope you would like my answer and would be brainiest one.

Answer 2

Given :

Dimension of the paper = 1.5m x 20cm

To find :

Area 'A' of the paper

Solution :

The dimension of the paper 1.5m x 20cm indicates that;

Length of the paper 'l' = 1.5m

Breadth of the paper 'b' = 20cm = (20/100)m = 0.2m

This dimension measures indicates that the paper is rectangular shaped.

Therefore, the Area of the paper = Length x Breadth

               ⇒ A = l x b

                    A = 1.5m x 0.2m = 0.3m² = 3000cm²

The area of the paper is 0.3m² or 3000cm²
