a. 31428

b. 31428.5

c. 31478

d. 314284/7





Two sides of a parallelogram are 20 cm and 25cm. If the altitude corresponding to the sides of length 25cm is 10cm, find the altitude corresponding to the other pair of sides:






ANSWER BOTH THE QUESTION ​

Answer 1

Answer:

option b is correct answer sis

2nd problem;

If the altitude corresponding to the sides of length 25 cm is 10 cm, find the altitude corresponding to the other pair of sides. Let ABCD is a parallelogram with longer side AB = 25 cm and altitude AE = 10 cm. ... Hence, the altitude corresponding to the other pair of the side AD is 12.5 cm.

★Explanation ★

1 ] Option ( B ) is correct answer

= ( 5 )31428.5

2 ]★ Explanation ★

We are given, that two sides of a parallelogram are 20 cm and 25 cm

Now,

Area of parallelogram = height (or Altitude) × base

here, Base QR is having altitude PT & Base SR is having altitude QU.

So, QR × PT=SR×QU

25 × 10 = 20 × QU

Now, QU = x so,

x = 20

25 × 10

= 12.5cm

So, the altitude corresponding to the other pair of sides is 12.5cm
