two cross - roads each 4m wide, run through, the centre of a rectangular park of dimensions 70m by 40m, are parallel to the length and other parallel to breadth. Find the cost of levelling the road at Rs 8 per m sq and also the cost of planting flowers in remaining part of park at Rs 6 per m
Answers
Step-by-step explanation:
Area of 1st Road = (70 × 4) m²
= 280 m²
Area of 2nd Road = (40 × 4) m²
= 160 m²
Area of portion that is common
= (4 × 4) m² = 16 m²
Area of both roads = ( 280 + 160 - 16) m²
= 424 m²
Cost of leveling the road = ₹ ( 424 × 8)
= ₹ 3,392
Area of rectangle Park = ( 70 × 40) m²
= 2800 m²
Area of remaining park = ( 2800 - 424) m²
= 2376 m²
Cost of planting flowers = ₹ ( 2376 × 6)
= ₹ 14, 256.
Step-by-step explanation:
are of 1 st road =(70×4) m sq
280 m sq
area of sec road =(40×4) m sq
160 m sq
area of portion that is common (4×4) m sq = 16 m sq remain and is in the pic
