Question

in parallelogram ABCD AB is equals to 15 cm and altitude corresponding to the sides A B and C are respectively 10 cm and 7.5 cm find ad.

Answer 1

Answer:

AD = 20 cm

Step-by-step explanation:

AB = base = 15 cm

let CE be the altitude corresponding to side AB = h = 10 cm

area of parallelogram ABCD = b × h = 15 × 10 = 150 sq cm

taking AD as base

and AF as the altitude corresponding to base AD

AD = b

AF = h = 7.5 cm

we know that the area of parallelogram ABCD is 150 sq cm

150 = b × 7.5

b = 150/7.5

b = 20

therefore AD = 20 cm

hope you get your answer

Answer 2

Hola mate

Here is your answer -

AB = base = 15 cm

let CE be the altitude corresponding to side AB = h = 10 cm

area of parallelogram ABCD = b × h = 15 × 10 = 150 sq cm

taking AD as base

and AF as the altitude corresponding to base AD

AD = b

AF = h = 7.5 cm

we know that the area of parallelogram ABCD is 150 sq cm

150 = b × 7.5

b = 150/7.5

b = 20

therefore AD = 20 cm
