Answer:

dimensions of rectangle is 45 cm n 30 cm

Step-by-step explanation:

let the breadth of rectangle be x cm

let the length of rectangle be 15+x cm

perimeter of rectangle is 150 cm

ATQ

perimeter of rectangle=2(l+b)

150=2(15+x+x)

150=30+2x+2x

150=30+4x

150-30=4x

120=4x

120/4=x

30=x

so,the length of rectangle is 15+x

15+30=45 cm

breadth of rectangle is x =30 cm

perimeter of rectangle=2(l+b)

=2(45+30)

=2(75)

150 cm

hence proved...

hopefully it helps you

Answer 2

GOOD MORNING!))

let the breadth of rectangle be = xcm

Then it's length would be = (15 + x)

Perimeter of rectangle = 2(length + Breadth)

Here, perimeter = 150cm ,

length = (15 + x)cm

And

Breadth = xcm

So,

150 = 2{(15 + x)+ x }

150 = 2{ 15 + 2x}

75 = 15 + 2x

2x = 75 - 15

2x = 60

x = 30

So, Breadth of RECTANGLE is 30cm

Ans

it's length is (30 + 15) = 45cm
