Question

find the area of a triangle two sides of which are 60cm 100cm and perimeter is 300cm​

Answer 1

Answer:

Given: P=300cm;

a= 60cm;

b=100cm.

Solution: P= a+b+c

300= 60+100+ c

c= 140cm.

s= a+ b+ c/2

s= 150cm.

A = √[s(s-a)(s-b)(s-c)]

= √[150(150-60)(150-100)(150-140)]

= √[150(90)(50)(10)]

= √[13500*500]

= √6750000

= 2598.07cm^2
