Mathematics Question and Solution
Observing similar plane shape (right-angled) side length ratios.
(6+x) - (6+2+6)
6 - 8
Cross Multiply.
8(6+x) = 6(14)
48+8x = 84
8x = 84-48
8x = 36
x = ½(9) units.
Again;
Observing similar plane shape (right-angled) side length ratios.
6 - y
(6+½(9)) - ½(9)
Cross Multiply.
27 = 10.5y
27 = ½(21)y
y = (2*27)/21
y = ⅐(18) units.
Shaded Area Pink is;
½(xy)
= ½*½(9)*⅐(18)
= (81/14) square units.
= 5.7857142857 square units.
