Answer: 2400
Explanation: By PGT 60^2 + 80^2 = 100^2
3600 + 6400 = 10000
Base = 60 or 80

Area = * Base * Height
Area = * 60 * 80
Area = 2400

Answer:
2400
Explanation:
s= a+b+c/2
s=100+80+60/2
=120
from herons formula =√s(s-a) (s-b)(s-c)
=√120(120-100)(120-80)(120-60)
=√120*20*40*60
=√20*6*20*20*2*20*3
=√20^4 *6^2
=20^2 *6
=400*6
=2400
