Answer 2

Solution :-

Let,

• Length = 9x.

• Breadth = 7x.

And,

Perimeter = 144m.

We have to find,

Its Sides.

Formula Used,

Perimeter = 2(Length + Breadth)

Substitute the Values.

➝ 144 = 2(9x + 7x)

➝ 144 = 18x + 14x.

➝ 144 = 32x.

➝ x = 144/32.

➝ x = 4.5

Now,

• Length Of Rectangle = 9x = 40.5

• Breadth Of Rectangle = 7x = 31.5

Verification :-

➝ 2(40.5 + 31.5) = 144

➝ 2(72) = 144

➝ 144 = 144

HENCE, VERIFIED.

Hence, The Dimensions Of the Rectangle are 40.5 and 31.5 metres.
