Answer 1

Step-by-step explanation:

total area = 3.2*1.35m

total area=4.32

length=4.32/0.9m

4.8m

total cost=20*4.8

=96 rs

Answer 2

The length of the canvas is 4.8 m

Cost of the canvas is Rs. 103.68

Step-by-step explanation:

length of the board = 3.2 m

width of the board = 1.35 m

area of the board = length × breadth

area of the board = 3.2 ×1.35  = 4.32 m²

width of the canvas = 90 cm = 0.90 m

we need to find the length of canvas

area of canvas = area of the board

area of canvas = length × breadth

4.32 = length ×0.90

length = $\frac{4.32}{0.90}$

length = 4.8 m

cost of the canvas per meter = Rs. 24

cost of the canvas  = 24× 4.32 = Rs. 103.68

hence ,

The length of the canvas is 4.8 m

Cost of the canvas is Rs. 103.68
