(1 Point
1320 sq.m
1300 sq.m
1400 sq.m
1420 sq.m​

Answer 1

Answer:

1320 sq.m

Step-by-step explanation:

3) The sides of a triangle are 122 m, 22 m and 120 m respectively. The area of the triangle is:

a. 1320 sq.m

b. 1300 sq.m

c. 1400 sq.m

d. 1420 sq.m

Answer/ Explanation

Answer: (a)

Explanation: Given,

a = 122 m

b = 22 m

c = 120 m

Semi-perimeter, s = (122+22+120)/2 = 132 m

Using heron’s formula:

\(A=\sqrt{s(s-a)(s-b)(s-c)}\)

Put the values of s, a, b and c, to get the answer equal to 1320 sq.m.

Answer 2

Step-by-step explanation:

Given,

a=122m

b=22m

c=120m

We have to find the area of triangle

Here,

Semi perimetre (s)=(a+b+c)/2

=(122+22+120)/2

=132

By Heron's Formula,

Area of Triangle=

$\sqrt{s(s - a)(s - b)(s - c)}$
