• Ok so first for the rectangle:

Use the formula: b•h

50 • 20 = 1000 ft2

• Next, the triangle:

Formula: b•h/2

Add the 10 and 50, which is 60.

60 • 20 = 1200

1200/2 = 600 ft2

• For the circle:

Formula: π • r^2

The radius is 10ft

3.14 • 10^2
3.14 • 100 = 314 (Whole circle)

Since we need half of the circle, we divide by 2 to split them.

314/2 = 157 ft2

• Now add all together:

1000 + 600 + 157 = 1757 ft2

Answer from: Quest

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.

step-by-step explanation:

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.
