Answer 1

☆ Solution ☆

Given :-

• The perimeter of the rectangle is 80 unit.

• The breadth of the rectangle is 20 unit.

To Find :-

• The length of the rectangle.

Step-by-Step-Explaination :-

Let,

• The length of the rectangle be L.

Now,

As we know that :-

Perimeter of rectangle = 2 ( length + breadth )

Where,

• The perimeter of the rectangle = 80 unit.

• The length of the rectangle = L

• The breadth of the rectangle = 20 unit.

Putting the respective value,

80 = 2 ( L + 20 )

80 = 2l + 40

80 - 40 = 2l

40 = 2l

40/2 = l

20 = l

Hence,

The length of the rectangle is 20 unit .

Answer 2

Answer=20

Explanation:

perimeter of rectangle=2(l+b)

80=2×(20+b)

80÷2=20+b

40-20=b

20=b
