Question

two side of a parallelogram are 30 cm and 40 cm if the altitude corresponding to the sides of length 30 cm is 10 cm find the altitude corresponding to the other pair of sides​

Answer 1

Answer:

7.5 cm

Step-by-step explanation:

B = 30 cm       b= 40 cm         H=10 cm     h=?

Area of parallelogram = B x H

=30 x 10

=300 cm squared

area of parallelogram = b x h

300 = 40 x h

300/40 = h

30/4 = h

15/2 = h

h = 7.5 cm

Answer 2

Given :

B = 30 cm      

b= 40 cm        

H=10 cm    

h=?

Solution

Area of parallelogram = B x H

⇒=30 x 10

⇒=300 cm squared

⇒area of parallelogram = b x h

⇒300 = 40 x h  

⇒300/40 = h

⇒30/4 = h  

⇒15/2 = h  

⇒h = 7.5 cm
