Question

The area of a rectangle 54 cm2. and its length =9cm. find :

A) tge widtg of the rectangle.
B) the ratio between the width of the rectangle and its length.
C) the ratio beetween the width of the rectangle and its perimeter.
​

Answer 1

A) 6cm

B) 2:3

C) 1:5

Explanation:

A) area of rectangle = width × length

54cm^2 = x × 9

x = 54 ÷ 9

width = 6cm

B) the width = 6cm

the length = 9cm

the ratio between the width and the length

=》6cm : 9cm

if you simplify, it becomes 2: 3

C) the perimeter of the rectangle

= (2 × width) + (2 × length)

= (2 × 6) + (2 × 9)

= 12 + 18

= 30 cm

the ratio between the width and the perimetet

=》 6cm : 30 cm

if you simplify, it becomes 1 : 5
