Question

20. A rectangular perc is 64 m long and 56 m breed Find the cost of
(a) leveling the park at R$450 per som
(b) fencing the park at Rs76.50 per metre​

Answer 1

Step-by-step explanation:

area of the park = length × breadth

area = 64×56

area = 3584 m²

cost of leveling the park = Rs 450/m²

total cost = 450 × area of the park

=Rs 450 × 3584

= Rs 1612800

perimeter of the park = 2( length + breadth )

perimeter = 2( 64+56)

perimeter = 2×120

perimeter = 240 m

cost of fencing = Rs 76.50

total cost = Rs 76.50 × 240

= Rs 18360
