Answer 1

Step-by-step explanation:

Given A floor design is made on the floor by joining 4 triangular tiles of dimensions 20 cm , 24 cm and 28 cm. Find the cost of tiles at the rate of Rs √6 per sq cm.

• Given Dimensions of the tiles are 20 cm, 24 cm and 28 cm
• By using heron’s formula we have,
•          s = ½ (20 + 24 + 28)
•              = 36
• Now Area = √s (s – a) (s -b) (s – c)
•                  = √36 (36 – 20) (36 – 24) (36 – 28)
•                   = √36 x 16 x 12 x 8
•                   = 6 x 4 √96
•                    = 24 x 9.79
•                    = 235.15
• The cost of  tile per sq cm = Rs √6
• Therefore cost of each tile will be 235.15 x √6
•                                                    = 235.15 x 2.449
•                                                    = Rs 575.99
•                                                    = Rs 576
