The length is 5 yd
The width is 1 1/5yd

Answer 1

6.75

Step-by-step

h= 3 yd multiply the length =5 yd and then multiply the width = 11/5yd

then you divided 11 and 5 if you get the answer then multiply to 15

then the answer is

Answer 2

49.2

Explanation:

First you do SA=2Lw+2Lh+2wh

So then you get 2 x 1 1/5 x 5 + 2 x 1 1/5 x 3 + 2 x 5 x 3

After doing the math, you get 12+7.2+30

Then you get 49.2
