Question

the perimeter of rectangle field is 70m and its length is 15 m longer than its breadth.the field is surrounded by a concrete path . find the area of the path

Answer 1

Answer:

250 cm2

Step-by-step explanation:

Answer 2

Answer:250 Square centimeters.

Step-by-step explanation:

Recall from: perimeter = 2L + 2w

but we do not have the breadth, let it be x

the length is 15 more than a breadth, so it is 15 + x

given perimeter =70m

therefore, 70=2(15+x) + 2x

                70 = 30 + 2x +2x

             70-30=4x

               40=4x

              10m = x which is our breadth'

therefore, Recall again from the formular of area of a rectangle

  Area = length x width

length= 15+x =15+10=25

breadth(width) = x=10

answer= 25m x 10m = 250m²
