Answer:

perimeter of rectangle = 2 (10+8) = 36

now t hnically joining 2 semi circled we need circumference of circle with radius = 8/4 = 2

so circum = 2 pi r = 2 pi 2 = 4 pi

now 4pi = 4 × 3.14 = 12.56

so total = 36 + 12.56 = 48.56

said to round nearest tenth so ans is 48.5

QUESTION 2 21 Write THREE equivalent actions for the following traction 25/50

MrMuchimi

The three equivalent fractions for $\frac{25}{50}$ are, $\frac{1}{2},\frac{5}{10},$ and $\frac{50}{100}$ .

<h3>What are equivalent fractions</h3>

Equivalent fractions are the fractions that have different numerators and denominators but are equal to the same value. For example, $\frac{2}{4}$ and $\frac{3}6}$ are equivalent fractions, because they both are equal to the $\frac{1}{2}$ . A fraction is a part of a whole. Equivalent fractions represent the same portion of the whole.

Given that:

$\frac{25/25=1}{50/25=2}$

$=\frac{1}{2}$

$\frac{25/5=5}{50/5=10}$

$=\frac{5}{10}$

$\frac{25*2=50}{50*2=100}$

$=\frac{50}{100}$

Therefore, The three equivalent fractions for $\frac{25}{50}$ are, $\frac{1}{2},\frac{5}{10},$ and $\frac{50}{100}$ .
