Question

Rectangle the primeter=40
2(....x+.....x)=40
2×....x=40
x=.....​

Answer 1

Question -

Perimeter of Rectangle = 40

2(......x + ......x) = 40

2 × .....x = 40

x = .....

Answer ==>

10

Explaination -

Given - Perimeter of rectangle = 40

We know that, Perimeter of Rectangle = 2(l+b)

So,

2(l+b) = 40

Now, According to question -

2(....x + .... x) = 40

....x + ....x = 40/2

2.....x = 20

....x = 20/2

..x = 10

Hence, x = 10

Verification -

2 (.....x + ....x) = 40

Putting X = 10

2(10 + 10 ) = 40

2 × 20 = 40

40 = 40

L•H•S = R•H•S

Verified.

Answer is absolutely right.

Length of Rectangle = 10

Breadth of Reactangle = 10
