The ratio of the longer side of a rectangle to its
shorter side is 4 to 3. if the shorter side of the
rectangle is 21 ft, what is the length of its longer side?

28 ft

Step-by-step explanation:

Given,

The ratio of the longer side of a rectangle to its shorter side=4:3

It is said that the length of the shorter side is 21 ft.

Let the longer side be x.

Then,

4:3=x:21

or,4/3=x/21

or,x=(4*21)/3=28 ft.[ANS]

it's both, now can you answer my most recent question?

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
