Answer:
34cm
Step-by-step explanation:
[Area of ||ogram=base x height]
=> 70=b*7
=> b=70/7 = 10cm.
AREA of parallelogram= AREA of rectangle
[Parallelogram and rectangle on same base and and between same parallels]
THEREFORE- L=10cm, B=7cm
(Breadth of rectangle is perpendicular to length)
Perimeter of rectangle = 2(L+B)
=> 2(10+7)
=> 2*17
=> 34cm
