Question

two sides of a triangular field 85 and 154 metre in the length and its perimeter is 324 find the area of field

Answer 1

all the best
thank you

Answer 2

The first side is = a = 85m
The second side is = b = 154m
The third side is = c = 324 - 85 - 154 = 85m
The semi perimeter = s = 324/2 = 162m
Area = [s(s - a)(s - b)(s - c)]^1/2
= [162 (162 - 85)(162 - 85)(162 - 154)]^1/2
= [162 * 77 * 8 * 77]^1/2
= 77 * 2 * 2 * 9
= 2772 m^2

The area is 2772 m^2...
