Question

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

Answer 1

Hey friends...!!!

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
