Answer:
D 2400 ft^2
Step-by-step explanation:
His joumey maps out a right angles triangle with base 80 and height 60.
The required area = 1/2 * 80 * 60
= 2400 ft^2
Probability(both marbles are red) = 5/12 * 4/11 = 20/132
= 5/33 Answer
A=2(L+W) A=2L+2W A-2L=2L-2L+2W A-2L=2W A-2L divided by 2=2W/2 A-2L divided by 2=W
