Answer 2

Answer:

Fraction of the wall coloured red = $\frac{3}{10}$

b. Fraction of the wall coloured orange $= \frac{1}{2}$

Area of orange colour = 12.5$m^{2}$

Step-by-step explanation:

Blue : Orange : Red = 2:5:3

Fraction of the wall coloured red = $\frac{3}{(2+5+3)}$ = $\frac{3}{10}$

b. Fraction of the wall coloured orange = $\frac{5}{(2+5+3)}$ = $\frac{5}{10} = \frac{1}{2}$

If the wall has an area of 25 square metres, then area of orange colour:

$\frac{1}{2} of 25$ = 12.5$m^{2}$
