Estimate the product of 23.725 ×6.25. then find the product why is it a good idea to estimate first

Given expression,

23.725 × 6.25

Since, it is quite tough to find the product of the above problem directly or without estimation,

Now,

23.725 ≈ 24,

6.25 ≈ 6

⇒ 23.725 × 6.25 ≈ 24 × 6 = 144

Hence, 23.725 ×6.25  ≈  144

Reason of estimation :

Since, after rounding the numbers we get the integers which are easy to multiply in compare to multiply the given decimal numbers.

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
