Sir solve this question....
Find the area of trapezium whose parallel sides are 25cm, 13cm and other sides are 15cm, 15cm.
Area of trapezium = ½ × sum of parallel side × sum of distance between parallel sides.
∴ ½ × (25+13) × (15+15)
= ½ × 38 × 225
= 4275cm2

sir if you check one thing in textbook the side c=120 then why are you taking 122 if we go according to textbook the answer will be complete different(Q2)??
Nice explanation
Sir Q2 Calculations are wrong
Let the sides of the triangular will be
a = 122m, b = 12cm, c = 22m
Semi-perimeter, s = a+b+c2
(122+120+224)m = 2642 m = 132m
The area of the triangular side wall
NCERT Solutions for Class 9 Maths Chapter 12 Heron's Formula Ex 12.1 Q2.1
Rent for 1 year (i.e. 12 months) per m2 = Rs. 5000
∴ Rent for 3 months per m2 = Rs. 5000 x 312
= Rent for 3 months for 1320 m2 = Rs. 5000 x 312 x 1320 = Rs. 16,50,000.

Bhai area nikalega to cm sqr m hi aayega na
Kyu ke cm is multiplayed by cm so we get cm²
Area ham cm² ya m² mtlb ham sqr mai hee laity hai 😊
Yass also want to know whyy??
Area = Square cm or m
