Question

16. The side of a rectangle are
in the ratio 3:1. If one side is 7
cm, the other side is​

Answer 1

Hey mate !!

Here is your answer:-

Let the one side be x

Let other side be 3x

Given x = 7

Then 3x = 3(7) = 21

Other side = 21cm.

Answer 2

Given :-

• The ratio of the rectangle sides is 3:1.
• If one side is 7cm.

To Find :-

• The other side of the rectangle.

Solution :-

Rectangle has two sides that are Breadth and Length.

Let's take one side be breadth.

Then breadth = 7cm.

Let length = 3x ( because rectangle has four sides. Here we have one side. So remaining 3 sides left. Hence 3x is given.)

Let x = 7 ( because one side is 7cm. So if we multiple 7 by 3 we get the answer.)

Hence, 3x = 3(7) = 21cm.

Length = 21cm.

Verification :-

Given ratio = 3:1.

Let 3 be length

Let 1 be breadth

Hence, 21/7 = 3:1

So, we get 3:1 . The given ratio also 3:1.

Hence our answer is correct.
