Answer 1

Question :

The perimeter of a rectangle is 13 cm and its width is 2 3/4 cm. Find its length.

Answer :

Given :

Perimeter = 13cm

Width = 2 3/4 cm = 11/4 cm = 2.75 cm (b)

Length = ? (l)

We know that

Perimeter = 2(length + breadth)

Apply in the question .

According to the question

13cm = 2(l + 2.75cm)

13cm = 2l + 5.5cm

13cm - 5.5cm = 2l

7.5cm = 2l

7.5cm/2 = l

3.75cm = length
