Answer: 2400 m^{2}

Explanation: By PGT 60^2 + 80^2 = 100^2

3600 + 6400 = 10000

Base = 60 or 80

Height = 80 or 60

Area =  \frac{1}{2} * Base * Height

Area = \frac{1}{2} * 60 * 80

Area = 2400 m^{2}

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
