Answer 1

I hope this will satisfy you

Answer 2

Answer:

$15 m \times 25 m$

Step-by-step explanation:

Let the breadth of rectangle be x

We are given that the length of a rectangle is 10m more than its breadth.

So, Lengthy of rectangle is x+10

Perimeter of rectangle =$2(Length +Breadth)$

                                      =$2(x+10 +x)$

                                      =$2(2x+10)$

                                      =$4x+20$

We are given that perimeter is 80m

So, $4x+20=80$

$4x=60$

$x=15$

So, Breadth = 15 m

Length = 15+10 = 25 m

Hence  the dimensions of the rectangle are$15 m \times 25 m$
