Carla made a border for her garden using parallelogram shaped tiles. Each piece had a base of 4 inches and a height of 2.5 inches. She used 85 tiles. What was the total area of the border

For each piece we have that the area is:

A = (b) * (h)

Where,

b: base of the parallelogram

h: height of the parallelogram

Substituting values:

A = (4) * (2.5)

A = 10 in ^ 2

Then, for 85 pieces we have:

(85) * (10) = 850 in ^ 2

Answer:

the total area of the border was:

850 in ^ 2
