Question

Two adjacent sides of a parallelogram are 10 cm and 15 cm. The altitude corresponding to the side is 5 cm is 9 cm. Find the altitude to the side of 10 cm.
(A) 9cm
(B) 12cm
(C) 13.5cm
(D) 9.5cm

Answer 1

Area of parallelogram = side * corresponding alititude

Given that altitude corresponding to the side 15 CM is 9cm.

Let the altitude to the side 10 CM is x.

Area of parallelogram = 15 * 9 = 135 .

In other ways, area = 10*x.

10x = 135 .

x = 135/10 = 13.5

Option C is correct.

Answer 2

Answer:

answer:− 

 

Area of parallelogram = side x corresponding alititude 

Given altitude of the corresponding side = 15 CM is 9cm. 

altitude to the side be 10 CM be x. 

Area of parallelogram = 15 × 9 = 135 .

area = 10×x.  

10x = 135 .

x=135/10

13.5cm //

therefore the altitude of corresponding to the side 10cm is 13.5 cmm
