In the parallelogram ABCD, DC=. 40cm. The altitude corresponding to sides AB and BC are 10cm and 12 cm respectively. Find the length of side CB?​

Answer 1

Answer:

using the formula of area of ||gm

using the formula of area of ||gm2

using the formula of area of ||gm21

using the formula of area of ||gm21

using the formula of area of ||gm21 ×AB×altitude1=

using the formula of area of ||gm21 ×AB×altitude1= 2

using the formula of area of ||gm21 ×AB×altitude1= 21

using the formula of area of ||gm21 ×AB×altitude1= 21

using the formula of area of ||gm21 ×AB×altitude1= 21 ×AD×altitude2

using the formula of area of ||gm21 ×AB×altitude1= 21 ×AD×altitude2AB×altitude1=AD×Altitude2

using the formula of area of ||gm21 ×AB×altitude1= 21 ×AD×altitude2AB×altitude1=AD×Altitude210×7=AD×8

using the formula of area of ||gm21 ×AB×altitude1= 21 ×AD×altitude2AB×altitude1=AD×Altitude210×7=AD×8AD=

using the formula of area of ||gm21 ×AB×altitude1= 21 ×AD×altitude2AB×altitude1=AD×Altitude210×7=AD×8AD= 8

using the formula of area of ||gm21 ×AB×altitude1= 21 ×AD×altitude2AB×altitude1=AD×Altitude210×7=AD×8AD= 870

using the formula of area of ||gm21 ×AB×altitude1= 21 ×AD×altitude2AB×altitude1=AD×Altitude210×7=AD×8AD= 870

using the formula of area of ||gm21 ×AB×altitude1= 21 ×AD×altitude2AB×altitude1=AD×Altitude210×7=AD×8AD= 870 =8.75
