Question

find the area of a triangular field whose sides are 25 m, 60 m, 65 m

Answer 1

Answer:

750m²

Step-by-step explanation:

Using the formulas

A=√s(s﹣a)(s﹣b)(s﹣c)

s=a+b+c/2

Solving forA

A = 1/4﹣a^4+2(ab)^2+2(ac)^2﹣b^4+2(bc)^2﹣c^4

=1/4·﹣25^4+2·(25·60)^2+2·(25·65)^2﹣60^4+2·(60·65)^2 -

65^4=750m²

Answer 2

Step-by-step explanation:

area of triangle =

$\frac{1}{2} \times base \: \times height$

the base and height are 60m and 25

(you can find this that by hypotenuse that is 65)

1/2 × 25m × 60m

25m × 30m

750m^2
