Question

Glass for picture frames sells for $20.00 per square meter. What is the total cost of the glass in two picture frames of which one is 62 centimeters by 34 centimeters and the other 44 centimeters by 64 centimeters? Round your answer to the nearest hundredths place.
 
The total cost is $

Answer 1

62 cm = .62 meters, 34 cm = .34 m, 44 cm = .44 m, 64 cm = .64 m

A = lw

A = .62(.34)

A = .2108 meters²

.2108 (20) = $4.216

A = lw

.44(.64) = .2816 meters²

.2816(20) = $5.632

5.632 + 4.216 = $9.85

 

Answer 2

First calculate Area of the glass Frames

1. 62X34=2108 sq cm

2. 44X64=2816 sq cm

 

total=4914 sq cm

1 sq m =10000 sq cm so 4914=0.4914 sq m

Secondly Multiply the frame size with the rate

$20/sq m X0.4914=$9.848

To the Nearest Cent, This is =$9.85

However it might be next to impossible to cut this piece of glass to such proportion so this is the ideal answer, the real one will depend on the dimensions of the Master frame he is cutting from and their allowed minimum size.
