Answer 1

Answer:

Answer:−

Given:-

The area of a rectangle is 240 m²

The length of the rectangle is 10m

To Find:-

The breadth of the rectangle. .

Solution:-

The length of the rectangle is 10 m ( given)

Let, the breadth of the rectangle be x m .

We know ,

Area of a rectangle = ( length × breadth ) square unit.

ATQ

➱ ( l × b ) = 240

➱ ( 10 × x ) = 240

➱ x = \dfrac{240}{10}

10

240

➱ x = 24

As,

breadth of the rectangle =( x )m = 24 m

so, the breadth of the rectangle is 24 m.

Formullas related to Rectangle:-

Area = ( length × breadth ) sq. unit

Perimeter = 2 × ( length + breadth ) unit.

Formullas related to square :-

Perimeter =( 4 × side )unit

Area = side² sq. unit .

Answer 2

Answer:

Correct option is C)

Let l be the length and b be the breadth

So according to the given condition l=3b

Perimeter=2(l+b)

So,2(3b+b)=240m

b=30m

So l=90m
