What is the area of triangle lmn?
a)12 square units
b)14 square units
c)15 square units
d)24 square units

Option A

12 square units

Explanation:

12 square units ie count up the vertical height of the triangle which is 6 units and then count up the horizontal length of it which is 4 so 6 x 4=24 for the rectangle formed by L x M but the triangle is only 1/2 of this area = 24/2= 12.

Hope this helps! :)

11

step-by-step explanation:

32.50-7.50=25

225/25=11

ratios represent a pattern or relationship that can be scaled.

equivalent ratios are pairs of ratios that represent the same relationship between quantities, and can be generated by multiplying or dividing both quantities in the ratio by the same factor.

in this lesson, students will use double number lines and ratio reasoning to solve ratio problems. by partitioning double number lines into proportionate intervals, students will build an understanding of equivalent ratio relationships as those that are generated by multiplying or dividing two related quantities by the same number. this lesson will build upon students' prior understanding of multiplicative comparisons, number line reasoning and equivalent fractions (while highlighting the difference between equivalent fractions and equivalent ratios); and will build toward future work in this unit on building ratio tables, and work in future grades in proportionality, scaling, and expressing and graphing linear functions.
