Question

if the ratio of the length to the breadth is 6:5 and area of the ractangle is 1080 square metre then find its length and breadth​

Answer 1

Answer:

Length is 36 m and Breadth is 30 m.

Step-by-step explanation:

Let length be 6x and Breadth be 5x.

Area = l ☓ b = 6x ☓ 5x = 30x^2

But area = 1080 m^2

So

30x^2 = 1080 m^2

x^2 = 36 m^2

x = 6 m.

➡️ Length = 6x = 6 ☓ 6 = 36 m

➡️ Breadth = 5x = 5 ☓ 6 = 30 m

Answer 2

Answer:

Step-by-step explanation:

Given ratio = 6:5

Let common ratio = x

Therefore, length = 6x

Breadth = 5x

Also area is given 1080 m^2

Area of rectangle = length × breadth

=6x × 5x

=30x^2 = 1080 m^2

Therefore, x^2=1080/30

×^2=36

Therefore x = 6m

Length = 6×6 = 36m

Breadth = 5×6=30m
