Question

The perimeter of a rectangle is 13 cm and its width is 2 whole 3/4 cm find its length in cm

Answer 1

Answer:

perimeter=13cm

width(b)=11/4

we know,

perimeter of rectangle=2(L+b)

therefore,

13cm=2(L+11/4)

13/2L+11/4

13/2-11/4=L

3.75 cm=L

Answer 2

Answer:

Solve for length

l=4.5cm

Width =2cm

Perimeter =13cm

Using the formula

P=2(l+w)

Solving for length

13 = 2(l + 2)

= 2l +4

2l = 13-4=9

$l = \frac{9}{2} = 4.5$
