You can factor a 12 out from both. 12 goes into 12m 12 times and 12 goes into 60 5 times. So you would pull it out front:
12(m+5)
That's as far as you can take it. Do you have to set it equal to 0, or some other number??
Best estimate of the area of a triangle = 100
.
Solution:
Given base of the triangle = 23.62 cm
Height of the triangle = 8.33 cm
Area of the triangle = 


Area of the triangle = 98.3773 
Estimation means rounded off to the closest correct answer.
98.3773 rounded off to 100.
Hence, best estimate of the area of a triangle = 100
.
It is less than two, so it has to be going in the direction that is below two. There is a line under the < so the dot should be filled. The answer is the third from the top. “Choice C”
