Answer:
the area of the glass is 1000cm^2
Step-by-step explanation:
Given that
The side is 50 cm
And, the power is 40 cm
We need to find out the area of the glass
So, the area of the glass is
= (50 × 40 ) ÷ 2
= 2,000 ÷ 2
= 1,000 cm^2
Hence, the area of the glass is 1000cm^2
The same is to be considered and relevant
.72 is a rational number
