The perimeter of parallelogram abcd is 30 cm. ad 3 cm more then twice ab. find the length of ab. a) 3 cm b) 4 cm c) 9 cm d) 11 cm

Option B.

Step-by-step explanation:

we know that

In a parallelogram opposite sides are congruent and parallel

so

the perimeter of parallelogram is equal to

we have

so

-----> ----> equation A

-----> equation B

Substitute equation B in equation A and solve for AB

c

step-by-step explanation:

multiply length by height. multiply the length by the height, and then double the product. work out 10 x 10 results = 100 square inches, then work out 100 x 2 = 200. the answer is 200 square inches.
