Question

The perimeter of a rectangle is70cm if the breadth of the rectangle to 5cm less than the length of the rectangle,find the area of the rectangle.​

Answer 1

Answer:

Perimeter =70cm

Breadth =5cm

Length =?

length of the rectangle=Perimeter/breadth

70/5cm

lenght = 14cm square

Area of a rectangle =L into B

5 into 14 cm

70cm square is answer

Answer 2

Answer:

The area of the rectangle is20sqcm

Step-by-step explanation:

The perimeter of the rectangle is 70cm .....given

Let the breadth of the rectangle be x and therefore the length will be x+5cm

According to the condition

Perimeter =2(l+b)

70. =2X2x+5

35. =2x+5

30. =2x

15. =x

Therefore x+5 =20

Therefore

Area =15*20

=300sqcm
