Question

a table top in the shape of parallelogram was polished at the rate of 20 rs per 10 cm^2. if the base of parallelogram is 45 cm and the total cost 2250 rs, find the altitude of the parallelogram

Answer 1

Answer:

Step-by-step explanation:

For table top,

base= 45cm

height (altitude) = ?

let, the height be 'x'.

Area of table top = base * height = 45*x= 45x

Cost= 2250 Rs

2250= rate * area

2250=20/10(as in question, it's given 20rs/10cm^2) * 45x

2250=2*45x

2250/2*45=x

25=x

x=25

Therefore, height of table top is 25 cm.

I hope this helps. Please give a thanks if possible! :)
