Answer 2

$\huge\sf\underline\blue{Solution}$

Given,

Length of rectangle is 22m

Breadth of rectangle is y (we have to find)

Area of rectangle =440m²

FORMULA:-

AREA OF RECTANGLE = LENGTH × BREADTH

So,

400m² = 22m × y

y =

\frac{440m²}{22m}

y=20m

So,breadth of rectangle is 20m

Perimeter =?

FORMULA:-

PERIMETER OF RECATANGLE = 2(l + b)

So, Already we know length and breadth

Perimeter = 2(22m +20m)

Perimeter = 2(42m)

Peeimeter = 84m

So, Final required answers are

Breadth of rectangle = 20m

Perimeter of rectangle = 84m
