1.	PLS ANSWER... Two adjacent sides of a parallelogram are in the ratio 5: 7. If the perimeter of the parallelogram is 72 cm, find the length of each of its side
Answer» llelogram perimeter = 2 (A+B) GIVEN 2(A+B) = 72 Then A + B = 36 Now, A : B = 5:7 => 7A = 5B => A = 5B/7 Put the above on A+B we get, 5B/7 + B = 36 => 12 B = 36*7 = 252 => B = 252/12 = 21. Then, A = 36 - 21 = 15. Therefore the LENGTH of both sides is 15 and 21

PLS ANSWER... Two adjacent sides of a parallelogram are in the ratio 5: 7. If the perimeter of the parallelogram is 72 cm, find the length of each of its side

Answer»

llelogram perimeter = 2 (A+B)

GIVEN 2(A+B) = 72

Then A + B = 36

Now, A : B = 5:7

=> 7A = 5B

=> A = 5B/7

Put the above on A+B we get,

5B/7 + B = 36

=> 12 B = 36*7 = 252

=> B = 252/12 = 21.

Then, A = 36 - 21 = 15.

Therefore the LENGTH of both sides is 15 and 21
