Length of wall around is 410m.one wall length is 80m.what is length of wall along it's breadth. What is area of ground

 Answer:

Breath of the wall: 125m

Area of the ground:10000m²

Explanation:

Breadth is a mathematical term describing the distance between a shape's right and left sides. You might think that the definition of breadth sounds similar to the definition of width. The terms breadth and width are interchangeable!

We briefly discussed the area earlier in the lesson, so let's pick up where we left off. The area of a shape tells us how much space there is inside it. The area of a rectangle will be the focus of this lesson.

To calculate the area of a rectangle, multiply its breadth or width by two of its dimensions, such as its height or length. Let us calculate the area of this blue rectangle.

    perimeter = 2(l+b)

    410m = 2(80+b)

               =160+2b

        2b = 410-160

            = 250

        b =250/2

        b=125

therefore a breath of the wall 125m.

Area of the wall = lb

                            =80*125

                            =10000m²

therefore the area of the wall is 10000m²
