Question

A field is 58m long and 30m wide.It has two roads one parallel to its length and one parallel to its breadth. find the area of the cross roads if each is 2m wide​

Answer 1

Answer:

172m²

Step-by-step explanation:

Let ABCD and PQRS be the across roads,

We have,

AB = 2m

BC = 58 m

Area of the ABCD = AB x BC

= 2 * 58 m square

= 116 m square

PQ = 2m

QR = 30m

Area of the PQRS = PQ x QR

= 2 x 30 m square

= 60 m square

EF = 2m

FG = 2m

Area of EFGH = EF x FG

= 2 x 2 m square

= 4 m square

Total area of roads = area of ABCD + Area of PQRS - area of EFGH

= 116 m sq + 60 m sq - 4 m sq

= 176 m sq - 4 m sq

= 172 m sq

So, area of roads = 172 m square
