Chapter 8: Q. 20 (page 541)

Find the area of a triangle whose sides area=4.b=5,c=3.

Short Answer

Expert verified

Required area of the triangle is 6squareunits.

Step by step solution

01

Step 1. Given information

The area of a triangle with sides a, b, and c is determined by the Heron's formula which is given as:

Area=s(s-a)(s-b)(s-c)where,s=(a+b+c)2

02

Step 2. Calculation

Given,a=4,b=5,c=3Then,s=a+b+c2=4+5+32=122=6Now,Heron'sFormulagivesareaasArea=ss-as-bs-c=66-46-56-3=6脳2脳1脳3=36=6squareunits.
