Question

the ratio of adjacent sides of a rectangle is5:2 if perimrter of rectangle is 56cm then what is the length and breadth of rectangle
​

Answer 1

Answer:

ANSWER

Let length =5x and breadth=2x

Area of rectangle=5x×2x=10x

2

Perimeter of rectangle=2(l+b)=2×(5x+2x)=14x

Now,

A

P

=

3

1

⇒

10x

2

14x

=

1

⇒x=4.2

∴Length of rectangle=5×4.2=21 units.

Answer 2

⇒x=4.2

∴Length of rectangle=5×4.2=21 units.

Step-by-step explanation:

Rectangles have four sides, and generally the adjacent sides are not equal. Knowing the measurements of the two sides allows you to create a ratio of the rectangle. ... Divide the ratio, then set the bottom number to one. In the example, 8 divided by 4 equals 2. So your ratio is 2 to 1.
