Question

A Private Rectangular swimming pool has length of 20 m and breadth of 17 m The swimming surrounded by walkway of breadth 1.5 m find the area

Answer 1

Answer:

Area  = 460 m²

Step-by-step explanation:

Given the length  of swimming pool = 20m

                  breadth of swimming pool= 17m

Breadth of walkway = 1.5m

So the total length of swimming pool becomes l =20 + 2×1.5

                                                                                 =20 +3= 23m

Total breadth of swimming pool becomes b = 17 + 2×1.5

                                                                          = 17 + 3= 20m

Area= length× breadth  = 23 × 20 = 460 m²
