Question

If RENT is a parallelogram. If RE=9.5 cm and perimeter is 30 cm, find RT

Answer 1

Answer:

ANSWER

We know that the perimeter of parallelogram ABCD can be write as

Perimeter =AB+BC+CD+DA

We know that opposite sides of parallelogram are equal

AB=CD and BC=DA

By substituting the values

Perimeter =9.5+BC+9.5+BC

It is given that perimeter =30cm

so we get

30=19+2BC

It can be written as

2BC=30−19

By subtraction

2BC=11

We get

BC=5.5cm

therefore, AB=9.5cm, BC=5.5cm, CD=9.5cm and DA=5.5cm
