When choosing the shirts it doesn't matter what order they're chosen in because at the end you'll have the same four shirts ... so it's a combinations question (rather than a permutations question where the order of choice makes a difference)
<span>so number of groups = 6C4 = 15 </span>
<span>another way is to evaluate 6P4 / 4! = 360/24 = 15

Shape 1: TRIANGLE
Formula: A = 1/2 x bh
1/2 x (10)(5) = 25
AREA: 25 square yards
Shape 2: RECTANGLE
Formula: A = lw
(12)(10) = 120
AREA: 120 square yards
Sum (ADD)
25 yd^2 + 120 yd^2 = 145 yd^2
The area of the composite figure is 145 yd^2
