Question

1.     The area of a square is less than 25cm2. What can we say about

a.     The length of one of its sides?

b.    Its perimeter?​

Answer 1

Explanation:

area= 25cm squared

length of one side = 5cm as 5*5 =25

perimeter= 5*4= 20cm

But since the area is less than 25cm squared

we can say that the length of one side is less than 5cm and we can also say that the length of the perimeter is less than 20cm.

Hope this helps.

Answer 2

Explanation:

Let us take a nominal square of area 25 cm².

• It's length of one of it's sides will be √25 = 5 cm².
• It's perimeter will be 5*4 = 20 cm.

So, in this question, we can say that:-

a. The length of one of its sides will be less than 5 cm.

b. Its perimeter will be less than 20 cm.

Hope it helps :)
