Question

Find the area of the cross roads at right angles to each other through the centre of a
rectangular field whose dimensions are 60 m x 45 m and the cross roads are 3 m wide.

Answer 1

Answer:

The area of the cross roads is 306 m²

Step-by-step explanation:

Given : Cross road width = 3 m

             Field length = 60 m

             Field width = 45 m

Solution : Two crossroads run at right angles through the centre of the field

               Consider the two  cross roads are parallal to length and width of

               the field.

then dimension of roads will be (60 x 3) + (45 x  3), and as they are overlapping at the centre, we have to deduct 3 x 3

∴ Total area of road = (60 x 3) + (45 x 3) - (3 x3)

                                 = 180 + 135 - 9

                                 = 306 m²
