A rectangular garden is going to be planted in a person’s rectangular backyard, as shown in the accompanying diagram. Some dimensions of the backyard and the width of the garden are given. Find the area of the garden to the nearest square foot.
ANS: 162. The legs of the triangle formed by the garden in the corner of the rectangular backyard are 10 (80-70) feet and 25 (40-15) feet. Use Pythagoras to determine the length of the garden.
10^2+25^2=c^2
725=c^2
sqrt(725) =c
A=lw=6sqrt(725)~~ 162.
