Question

an field 58m long and 30m wide has two cross roads one parallel to its length and the other parallel to its width. finfld the area of the cross roads if each is 2m wide.​

Answer 1

Answer:

Area of cross roads= area of vertical road+ area of horizontal road - area of intersection of two roads

Area of cross roads=(22×2.5)+(30×2.5)−(2.5×2.5)m

2

=55+75−6.25=123.75m

Answer 2

Step-by-step explanation:

area of a rectangle = length × breadth

area of a rectangle field =58 ×30 =1740 m²

length and breadth of 1 cross road respectively = 30 m and 5m

area of 1 cross road =30 ×2 =60 m²

area of 2 cross road =58 ×2 =116 m²

area of both the roads =116+60 176 m²
