Answer:
Rs 1304
Step-by-step explanation:
Area of rhombus tiles
= 1/2 * d1*d2 *400
= 1/2 * 18 *12 *400 =
=12*9*400
=108*400
=43200 cm2
Area of trapezium tiles
= 1/2* (d1 + d2) *h * 250 =
= 1/2 * (10 + 12) *8 * 250
= 1/2 *22 * 8 * 250
= 11 * 8 * 250
- 22000 cm2
Total area = 43200 + 22000
=65200 cm2
= 65200/100*100 m2
= 6.52 m2
Total cost = 6.52 * 200 =
- Rs 1304
