Answer 1

You haven't mentioned the time for the rent. but it's okay I'm solving without time.

Answer:

Formula for Area of triangle

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

Step-by-step explanation:

Given sides are 122m 22m and 120 m.

perimeter = 122+22+120 = 264 m

semi perimeter (s) =

$\frac{264}{2}$

= 132 m

Now, Rent per square meter = ₹200

rent for 132 m = 132 × 200 = ₹26400

Hence answer is ₹26400.

Hope, it helps you.
