Question

A total of 349 square meters of fabric covers The Pavilions 80 panels. The area of the 30 panels is 4 square meters each and another 30 are 4.3 square meters in area what is the area of each of the remaining 20 panels?

Answer 1

Answer:

 Area of each of the remaining 20 panels =  5 m²

Explanation:

 Total area of panels = 349 m²

 Total number of panels = 80

 Total area of 30 panels with 4 m² area = 30 x 4 = 120 m²

 Total area of 30 panels with 4.3 m² area = 30 x 4.3 = 129 m²

 Remaining number of panels = 20

 Remaining area = 349 - ( 120 + 129 ) = 100 m²

Area of each 20 panels = 100/20 = 5 m²

Area of each of the remaining 20 panels =  5 m²
