Answer 1

here is your answer if I'm not wrong

Answer 2

solution : The lengths of the sides of the walls are 122m,22m and 120m
we have,
$122 {}^{2} = 120 {}^{2} + 20 {}^{2}$
so,walls are in the form of right triangle.
therefore Area of two walls =
$2 \times ( \frac{1}{2} \times base \times height)$

so put value
area of two walls =
$2 \times ( \frac{1}{2} \times 120 \times 22) = 2640m {}^{2}$
we have,
yearly rent=5000 per metre square
montly rent=(5000/12)meter per square
hence,rent paid by the company for 3 months =(5000/12×3×2640)
3300000
