Q.2 The OPQRS alongside is the map of land
using the given measures, find its area,​

Answer 1

Answer:

answer.1= 204m^2

Step-by-step explanation:

suppose triangle is ABC

IF AB=17 ,BC=25,AC=26

use the formula of heron

first we find a semi parameter

a=AB=17,b=BC=25 and c=AC= 26

s=( a+b+c)÷2

=(17+25+26)÷2

=(68)÷2

s=34

now we take the formula of heron for triangles

$area \: of \: triangles = \: \sqrt{s(s - a)(s - b)(s - c)}$

put the value in formula

$= \sqrt{34(34 - 17)(34 - 25)(34 - 26)} \\ = \sqrt{34 \times 17 \times 9 \times 8} \\ = \sqrt{41616} \\ s = 204$

so the are of the triangles is

$204 {m}^{2}$

I hope its help to you
