A rectangular garden has a length of 15 meters and a width of 8 meters. The garden is surrounded by a path that is 2 meters wide on all sides. What is the area of the garden itself (excluding the path)?
Garden length = 15 meters – 2 meters – 2 meters = 11 meters
Garden width = 8 meters – 2 meters – 2 meters = 4 meters
Area = length × width
For the garden:
Area = 11 meters × 4 meters = 44 square meters
So, the area of the garden (excluding the path) is 44 square meters.

A rectangular garden is 15 m long and 8 m wide. The gardener also measured the distance from the corner of the garden to a tree 3.5 m from the corner along the length of the garden, and from the same corner to a shed 4.2 m away along the width of the garden. Additionally, the gardener marked the spot where the fence will start with a stake 0.5 m from the garden's starting point, and there are 4 equally spaced markers along each side of the rectangle. If a fence is placed around the garden, what is the total length of the fence needed?
P=2×(15m+8m)=2×23m=46m
