If the sum of the lengths of two adjacent sides of a parallelogram is 38 cm, then what is the perimeter of the parallelogram?
Answers
Answer:
Assuming the adjacent sides are “a” and “b” and a is the longer side,
Assuming the adjacent sides are “a” and “b” and a is the longer side,a - b = 5cm
Assuming the adjacent sides are “a” and “b” and a is the longer side,a - b = 5cmThe perimeter of the parallelogram is 58cm - i.e. 2(a+b) = 58cm
Assuming the adjacent sides are “a” and “b” and a is the longer side,a - b = 5cmThe perimeter of the parallelogram is 58cm - i.e. 2(a+b) = 58cmIf a – b = 5cm, then a = 5cm + b
Assuming the adjacent sides are “a” and “b” and a is the longer side,a - b = 5cmThe perimeter of the parallelogram is 58cm - i.e. 2(a+b) = 58cmIf a – b = 5cm, then a = 5cm + bRemember that 2(a+b) = 58cm.
