Answer 1

Answer: QB

Given; base of a parallelogram = 120cm

height of a parallelogram = 75cm

To find: area of a parallelogram?

Step-by-step explanation:

area of a parallelogram = b x h

(120 x 75)cm = 9000cm square

Answer 2

Answer:

(b) Area of parallelogram = 9000 cm² = 0.9 m²

(d) Total cost of levelling = ₹10500

Step-by-step explanation:

(b) Given: Base of parallelogram = 120cm , height of parallelogram = 75cm.

w.k.t., area of parallelogram with base b and height h is b×h.

⇒ Area of parallelogram = 120×75 = 9000 cm² = 0.9 m²

(d) Given: Length of rectangular courtyard = 70m , breadth = 30m.

w.k.t., area of rectangle with length l and breadth b is l×b.

⇒ Area of rectangular courtyard = 70×30 = 2100m²

It is given that, cost of levelling for 1m² area = ₹5

⇒ Cost of levelling for 2100m² area = 5×2100

or Total cost of levelling = ₹10500
