Answer:

256 m and 3840 m²

Step-by-step explanation:

The 3 part of the ratio represents 48 m , then

48m ÷ 3 = 16 m ← value of 1 part of the ratio, so

5 parts = 5 × 16 m = 80 m

Then breadth = 48 m and length = 80 m

perimeter = 2l + 2b = 2(80) + 2(48) = 160 + 96 = 256 m

area = lb = 80 × 48 = 3840 m²

Each circle counts as one whole, Write a mixed number giving the amount shaded. Then, write this amount as an improper fraction.

devlian [24]

Answer:

$2 \frac{2}{5}$

$\frac{12}{5}$

Step-by-step explanation:

As a mixed fraction, There are 3 circles with 5 pieces in each so our denominator will be 5

The number that is shaded is 2 whole circles so that is 10 and 2 out of 5 of last one.

The whole number is 2 and the fraction for the last circle is 2/5 so our mixed number is

$2 \frac{2}{5}$

Now to find the improper fraction turn 2 into a fraction with 5 as a denominator.

$\frac{2}{1} \times \frac{5}{5}$

Which equal

$\frac{10}{5}$

Then add 2/5 to 10/5

$\frac{10}{5} + \frac{2}{5} = \frac{12}{5}$
