If area of a square garden is 114m², find the lenghth of the garden .​

10.7m (3 s.f.)

Step-by-step explanation:

Since it is a square garden, the lengths of the garden are equal.

Area = 114m²

Length = m²

            = 10.7m (3 s.f.)

So, length of garden is 12m

30 Don't use your calculator.

Step-by-step explanation:

This is an estimation question, so you have to throw your calculator out of your reach.

You have to know that 66% is nearly 2/3 So the correct answer cannot be B or C

It must be A or D.

The problem is that 3 doesn't go into 46 so you have to change it to something that is divisible by 3. Of the numbers given, the best one is 45

2/3 * 45 = 2 * 15 = 30

How close is that (remember you have to give 30 as your answer)?

The actual answer is 30.36 which makes your estimate very good.
