Answers
Answer:
answer 1676.40
Step-by-step explanation:
area of outer - area of inner rectangle
8.2×19.7 -18.5 ×7
The total expense she will incur =Rs 939.6
Explanation:
Given : Length of garden = 18.5m
Width of garden = 7m
Area of garden = Length x Width = 18.5 x 7=129.5 sq. m.
Shahbano wants to build a path 60cm wide all around her garden
Since 1 cm = 0.01 m , then 60 cm = 0.60 m
Length of path ( included garden )= 18.5+0.60=19.1 m
Width of path ( included garden )= 7+0.60=7.6 m
Area of path= 19.1 x 7.6 - (Area of garden )
= 145.16- 129.5=15.66 sq. m
Rate of paving = Rs 60 per square meter
Cost of paving =( Rate of paving) x (Area of path )
= 60 x 15.66 = Rs 939.6
Hence, the total expense she will incur =Rs 939.6
